Since 1930 more than 100,000 new chemical compounds have been developed and insufficient information exists on the health assessment of 95 percent of these chemicals in which a relevant percentage are used in construction products. For instance Portland cement concrete, the most used material on the Planet (10.000 million tons/year that in the next 40 years will increase around 100 %) currently used in around 15% of total concrete production contains chemicals used to modify their properties, either in the fresh or hardened state. Biopolymers are materials that are developed from natural resources. They reduce dependence on fossil fuels and reduce carbon dioxide emissions. There is a worldwide demand to replace petroleum-based materials with renewable resources. Currently bio-admixtures represent just a small fraction of the chemical admixtures market (around 20%) but with environmental awareness for constituents in construction materials generally growing (the Construction Products Regulation is being enforced in Europe since 2013), the trend towards bio-admixtures is expected to continue. This book provides an updated state-of-the-art review on biopolymers and their influence and use as admixtures in the development of eco-efficient construction materials.

Dry stone retaining structures are structures made of individual decimeter stone blocks in contact. One advantage of this construction technology lies in the weak amount of embodied energy required for their construction, and uses only local materials. This technology may be a positive answer to the challenges brought by sustainable policies in civil engineering. Many of these structures are older than one hundred years and sustain damage due to ageing; this places the owners in front of a challenging issue. Usual scientific tools cannot address the specific behavior of such structures. Due to the discrete nature of the system, a large amount of energy can be dissipated at contact level before failure of the structure. The shape, arrangement and possible breakage of blocks may play a major role in their overall behavior, specific to these structures. This book brings an overview of the DEM technique to model the behavior of discrete civil engineering structures. Physical models, modeling and site measurements are all explored, helping the civil engineer evaluate the behavior of unique structures.

Koepriyet: Republican Heritage Bridges of Turkey deals with bridges and the construction industry of Turkey during the foundation of the Republic between 1923 and 1940. This book provides a brief summary of the bridge history of the country, but the main focus is on the Early Republic Era. During this period, the bridge-building technique was reborn in a country undergoing a radical transformation. Turkey changed its ruling, secularized and changed its alphabet. In addition to detailed descriptions of bridges built during this period and of leading innovative engineers, this book provides a first documented overview of heritage bridges in Turkey, focusing on applied techniques known worldwide. Many bridges are documented for the first time in this book, and most of them are heritage bridges and provide significant value in terms of bridge-building technology and application of worldwide techniques. In the waning days of the Ottoman Empire, engineering projects in Turkey were often carried out through "privileges" by foreign companies. The technical personnel were also financed with foreign resources. With the new Republic, Turkey experienced a renaissance in many areas, including technology. This transition from technology import to development and use of local resources is described in detail. Koepriyet: Republican Heritage Bridges of Turkey provides a wealth of information and documentation on bridges in Turkey from an important era, and aims at those interested in bridge structures and structural engineering history.

This book presents the foundation and validation of the Cosserat Plate Theory, numerical experiments of deformation and vibration, and the unique properties of the Cosserat plates. Our approach incorporates the high accuracy assumptions of the Cosserat plate deformation consistent with the Cosserat Elasticity equilibrium equations, constitutive formulas, strain-displacement and torsion-microrotation relations. The Cosserat Plate Theory is parametric, where the "splitting parameter" minimizes the Cosserat plate energy. The validation of the theory is based on the comparison with the three-dimensional Cosserat Elastostatics and Elastodynamics. The numerical results are obtained using the Finite Element Method (FEM) specifically developed to solve the parametric system of equations. The analysis of deformation of a variety of Cosserat plates shows the stress concentration reduction, higher stiffness of Cosserat plates, and the size-effect related to the microstructure. The analysis of vibration of Cosserat plates predicts size-related properties of the plate vibration, the existence of the additional so-called Cosserat plate resonances, and the dynamic anisotropy, related to the dependency of the resonances on the microelement's shapes and orientations.

Over the past few years there had been a dramatic increase in the number of women entering the surveying profession. Fewer than five per cent of practising surveyors were women, but women comprised twenty per cent of students. Originally published in 1991, Surveying Sisters explores the question of whether 'more' would mean 'better', either for women surveyors themselves, or for women as consumers of the built environment. Clara Greed investigates the experiences of individual women surveyors, as well as studying the nature of the male majority. Taking a broadly feminist perspective and using an ethnographic approach, she develops a strong theoretical basis, incorporating the gender, class, and spatial dimensions of the situation, centring round the concept that surveying has its own distinct professional subculture. She traces the historical roots of the profession, and its attitudes to women, and makes constructive suggestions for improving the position of women surveying today. This was a highly topical study, at a time when the surveying profession was eager to attract more women in order to allay the effects of declining numbers of school leavers and potential 'manpower' shortages. It will be of interest to people concerned about issues of gender in disciplines such as sociology, management studies, higher education, urban geography, and women's studies, and to the women and men who work in the surveying and other built environment professions.

This book adopts numerical method to model soil constitutive relationship while it abandons the traditional idea of looking for plastic potential as the only way to model. Firstly, the triaxial compression tests of expansive soil, sand and clay under different stress paths are introduced; then the elastoplastic constitutive equations of expansive soil, sand and clay under various stress paths are established by numerical modeling method; finally, the constitutive equations are embedded in the finite element program and verified by comparing the finite element calculation results of the triaxial test soil samples with the corresponding test results. The modeling obtains high accuracy.

The dramatic and enthralling story of the building of the Brooklyn Bridge, the world's longest suspension bridge at the time, a tale of greed, corruption, and obstruction but also of optimism, heroism, and determination, told by master historian David McCullough.
This monumental book is the enthralling story of one of the greatest events in our nation's history, during the Age of Optimism--a period when Americans were convinced in their hearts that all things were possible.
In the years around 1870, when the project was first undertaken, the concept of building an unprecedented bridge to span the East River between the great cities of Manhattan and Brooklyn required a vision and determination comparable to that which went into the building of the great cathedrals. Throughout the fourteen years of its construction, the odds against the successful completion of the bridge seemed staggering. Bodies were crushed and broken, lives lost, political empires fell, and surges of public emotion constantly threatened the project. But this is not merely the saga of an engineering miracle; it is a sweeping narrative of the social climate of the time and of the heroes and rascals who had a hand in either constructing or exploiting the surpassing enterprise.
