This book presents a hybrid approach to the mechanics of thin bodies. Classical theories of rods, plates and shells with constrained shear are based on asymptotic splitting of the equations and boundary conditions of three-dimensional elasticity. The asymptotic solutions become accurate as the thickness decreases, and the three-dimensional fields of stresses and displacements can be determined. The analysis includes practically important effects of electromechanical coupling and material inhomogeneity. The extension to the geometrically nonlinear range uses the direct approach based on the principle of virtual work. Vibrations and buckling of pre-stressed structures are studied with the help of linearized incremental formulations, and direct tensor calculus rounds out the list of analytical techniques used throughout the book. A novel theory of thin-walled rods of open profile is subsequently developed from the models of rods and shells, and traditionally applied equations are proven to be asymptotically exact. The influence of pre-stresses on the torsional stiffness is shown to be crucial for buckling analysis. Novel finite element schemes for classical rod and shell structures are presented with a comprehensive discussion regarding the theoretical basis, computational aspects and implementation details. Analytical conclusions and closed-form solutions of particular problems are validated against numerical results. The majority of the simulations were performed in the Wolfram Mathematica environment, and the compact source code is provided as a substantial and integral part of the book.

With high urbanization rates, advancement in technologies, and changes in consumption behavior of people, wastes generated through the daily activities of individuals and organizations pose many challenges in their management. The articles presented in this edited volume deal with the attempts made by the scientists and practitioners to address contemporary issues in geoenvironmental engineering such as characterization of dredged sediments, geomaterials & waste, valorization of waste, sustainability in waste management and some other geoenvironmental issues that are becoming quite relevant in today's world. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.

The ongoing population growth is resulting in rapid urbanization, new infrastructure development and increasing demand for the Earth's natural resources (e.g., water, oil/gas, minerals). This, together with the current climate change and increasing impact of natural hazards, imply that the engineering geology profession is called upon to respond to new challenges. It is recognized that these challenges are particularly relevant in the developing and newly industrialized regions. The idea beyond this volume is to highlight the role of engineering geology and geological engineering in fostering sustainable use of the Earth's resources, smart urbanization and infrastructure protection from geohazards. We selected 19 contributions from across the globe (16 countries, five continents), which cover a wide spectrum of applied interdisciplinary and multidisciplinary research, from geology to engineering. By illustrating a series of practical case studies, the volume offers a rather unique opportunity to share the experiences of engineering geologists and geological engineers who tackle complex problems working in different environmental and social settings. The specific topics addressed by the authors of chapters included in the volume are the following: pre-design site investigations; physical and mechanical properties of engineering soils; novel, affordable sensing technologies for long-term geotechnical monitoring of engineering structures; slope stability assessments and monitoring in active open-cast mines; control of environmental impacts and hazards posed by abandoned coal mines; assessment of and protection from geohazards (landslides, ground fracturing, coastal erosion); applications of geophysical surveying to investigate active faults and ground instability; numerical modeling of seabed deformations related to active faulting; deep geological repositories and waste disposal; aquifer assessment based on the integrated hydrogeological and geophysical investigation; use of remote sensing and GIS tools for the detection of environmental hazards and mapping of surface geology. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.

This book analyses the effects of moving loads on elastic and inelastic solids, elements and parts of structures and on elastic media, namely beams, continuous beams, beams on elastic foundations, rigid-plastic beams and thin-walled beams, frames, arches, strings, plates, elastic spaces and half spaces, etc. It provides theoretical formulations for the problems, and mathematical solutions for all cases and their application to civil, mechanical, transport, naval and aircraft structures. The extensive and up-to-date bibliography gives a worldwide survey.

This book presents and applies a novel efficient meta-heuristic optimization algorithm called Colliding Bodies Optimization (CBO) for various optimization problems. The first part of the book introduces the concepts and methods involved, while the second is devoted to the applications. Though optimal design of structures is the main topic, two chapters on optimal analysis and applications in constructional management are also included. This algorithm is based on one-dimensional collisions between bodies, with each agent solution being considered as an object or body with mass. After a collision of two moving bodies with specified masses and velocities, these bodies again separate, with new velocities. This collision causes the agents to move toward better positions in the search space. The main algorithm (CBO) is internally parameter independent, setting it apart from previously developed meta-heuristics. This algorithm is enhanced (ECBO) for more efficient applications in the optimal design of structures. The algorithms are implemented in standard computer programming languages (MATLAB and C++) and two main codes are provided for ease of use.

Prepared by the Minimum Design Loads and Associated Criteria for Buildings and Other Structures Standards Committee of the Codes and Standards Activity Division of the Structural Engineering Institute of ASCEMinimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-22, provides the most up-to-date and coordinated loading provisions for general structural design. This standard prescribes design loads for all hazards including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, seismic, wind, and fire, as well as how to evaluate load combinations. The 2022 edition of ASCE 7, which supersedes ASCE 7-16, coordinates with the most current structural material standards including those from ACI, AISC, AISI, AWC, and TMS. Significant technical changes include the following: new target reliability tables for tsunami and extraordinary loads; new alternative method for loads from water in soil; terminology change from guardrail system to guard system; new provisions for emergency vehicle loads; updated tsunami data for Hawaii and many populous locations in California, coordinated with the state agencies; new tsunami provisions for above-ground horizontal pipelines; revised ground snow loads to reflect more recent snow load data and reliability-targeted values; revised method for estimating drifts to include a wind parameter; design rain load revisions to explicitly consider a ponding head; new risk-targeted atmospheric ice load data for the continental United States and Alaska; multi-period response spectrum data that eliminates need for Fa and Fv coefficients; new lateral force resisting systems such as steel and concrete coupled composite plate shear walls, reinforced concrete ductile coupled shear walls, cross-laminated timber shear walls, and concrete tabletop structures; new provisions for rigid wall, flexible diaphragm buildings (big box stores/warehouses); new and updated provisions for supported and interconnected (coupled) nonbuilding structures; new wind provisions for MWFRS and C&C of elevated buildings; new chapter of tornado provisions; new long return period hazard maps for wind and tornado; and digital data available for all hazards at ASCE Hazard Tool (https://asce7hazardtool.online/). In addition to the technical changes, the 2022 edition of ASCE 7 provisions are accompanied by detailed commentary with explanatory and supplementary information developed to assist users of the standard, including design practitioners, building code committees, and regulatory authorities. Standard ASCE/SEI 7 is an integral part of building codes in the United States and around the globe, and is adopted by reference into the International Building Code, International Existing Building Code, International Residential Code, and NFPA 5000 Building Construction and Safety Code. Structural engineers, architects, and those engaged in preparing and administering local building codes will find the structural load requirements essential to their practice.

It is estimated that 225,000 bridges, including nearly 40% of highway bridges, in the United States today are structurally deficient or functionally obsolete. While the urgency of this problem has begun to be acknowledged at official levels, and more public funds set aside for bridge inspection and rehabilitation, the need remains for engineers versed in contemporary rehabilitation methods. Unfortunately, until the publication of this book, engineers' efforts to educate themselves in the field have been thwarted by the fact that good, up-to-date material on bridge inspection and repair could be obtained only through a painstaking search through hundreds of specialized publications. Edited by Louis G. Silano, P.E., Senior Vice President and Technical Director of Structures with the firm of Parsons Brinckerhoff, Bridge Inspection and Rehabilitation: A Practical Guide is the first and only "A-to-Z" guide to practical aspects of bridge inspection and rehabilitation. Comprising contributions from a group of seasoned professionals from around the nation, it provides insights into every element of bridge structure, including broad coverage of materials and design types. Among important topics covered in Bridge Inspection and Rehabilitation are: advances in inspection techniques, including underwater inspection and nondestructive testing; all bridge design types, including suspension bridges, cable-stayed bridges, trusses, moveable bridges, and others; basic structural elements, such as substructures, superstructures, decks, bearings, and joints; and special topics of contemporary concern, such as seismic design and seismic retrofitting, environmental control issues, maintenance of trafficduring rehabilitation, repair of historical bridges, and much more. Generously illustrated with nearly 200 line illustrations and photographs and offering in-depth coverage of most practical aspects of bridge assessment and repairs, Bridge Inspection and Rehabilitation is an invaluable resource for practicing bridge engineers and contractors.

Well-designed hybrid structures can combine the different performance strengths of each material. This guide focuses on design approaches for concrete structures reinforced in an unconventional way by steel profiles. It explains force transfer mechanisms at steel profile-concrete interfaces and the peculiarities of the analysis of hybrid structures, including slender members. Several types of hybrid designs are addressed: walls and columns with several embedded steel profiles, connections strengthened by steel profiles between steel, and composite or reinforced concrete members, including the specific case of shear keys connecting deep beams or flat slabs to columns. The transition zones in partly RC and partly composite columns are also covered. Design of Hybrid Structures draws on the European Smartcoco research project, of experimentation and numerical modelling, giving practical guidance for designers and introducing the subject for researchers and graduate students.

Natural Gas Hydrates, Fourth Edition, provides a critical reference for engineers who are new to the field.

Rounding out with new case study examples, this new edition gives engineers an important tool to continue to control and mitigate hydrates in a safe and effective manner.

The book analyzes a quasi-static fracture process in concrete and reinforced concrete by means of constitutive models formulated within continuum mechanics. A continuous and discontinuous modelling approach was used. Using a continuous approach, numerical analyses were performed using a finite element method and four different enhanced continuum models: isotropic elasto-plastic, isotropic damage and anisotropic smeared crack one. The models were equipped with a characteristic length of micro-structure by means of a non-local and a second-gradient theory. So they could properly describe the formation of localized zones with a certain thickness and spacing and a related deterministic size effect. Using a discontinuous FE approach, numerical results of cracks using a cohesive crack model and XFEM were presented which were also properly regularized. Finite element analyses were performed with concrete elements under monotonic uniaxial compression, uniaxial tension, bending and shear-extension. Concrete beams under cyclic loading were also simulated using a coupled elasto-plastic-damage approach. Numerical simulations were performed at macro- and meso-level of concrete. A stochastic and deterministic size effect was carefully investigated. In the case of reinforced concrete specimens, FE calculations were carried out with bars, slender and short beams, columns, corbels and tanks. Tensile and shear failure mechanisms were studied. Numerical results were compared with results from corresponding own and known in the scientific literature laboratory and full-scale tests.

In the 21st century, architects and engineers are being challenged to produce work that is concurrently sustainable and resilient. Buildings need to mitigate their impact on climate change by minimising their carbon footprint, while also countering the challenging new weather conditions. Globally, severe storms, extreme droughts and rising sea levels are becoming an increasingly reoccurring feature. To respond, a design process is required that seeks to integrate resiliency by building in the capacity to absorb the impacts of these disruptive events and adapt over time to further changes, while simultaneously being part of the solution to the problem itself. This issue of AD is guest-edited by the interdisciplinary team at Stevens Institute of Technology who developed the winning entry for the 2015 US Department of Energy Solar Decathlon competition, the SU+RE House. While particular focus is paid to this student designed and built prototype home, the publication also provides a broader discussion of the value of design-build as a model for tackling the issue of integrating sustainability and resilience, and what changes are required across education, policy, practice and industry for widespread implementation. Contributors include: Bronwyn Barry, Michael Bruno, Alex Carpenter, Adam Cohen, Ann Holtzman, Ken Levenson, Brady Peters, Terri Peters, Karin Stieldorf, Alex Washburn, Claire Weisz, and Graham Wright. Featured architects: 3XN/GXN, FXFOWLE Architects, Local Office Landscape Architecture (LOLA), Lateral Office, Skidmore, Owings & Merrill (SOM), Snohetta, Structures Design Build, and WXY Studio.

The fifteen chapters of this book are arranged in a logical progression.

Safety and reliability are important for the whole expected service duration of an engineering structure. Therefore, prognostical solutions for different building types are needed and uncertainties have to be handled. Life-cycle strategies to control future structural degradations by concepts of appropriate design have to be developed, in case including means of inspection, maintenance, and repair. Aspects of costs and sustainability also matter. The Cooperative Research Center for Lifetime-Oriented Design Concepts (SFB 398) at Ruhr University in Bochum combines the wide range of scientific topics between structural engineering, structural and soil mechanics and material sciences regarding structural lifetime management in this present extraordinary monolithic format. The characterization and modeling of lifetime-related external actions of multiple origin are presented in this book as well as the physical description, the modeling and the validation of material degradation. Adaptive numerical methods and simulation techniques are provided for the lifetime-oriented design concepts to forecast material and structural degradation. Stochastic aspects, mathematical optimization methods and interactions between various influences are included. Thus, a solid basis is provided for future practical use and also for standardization of structural design with respect to lifetime-prediction.
