The Discrete Element Method (DEM) has emerged as a solution to
predicting load capacities of masonry structures. As one of many
numerical methods and computational solutions being applied to
evaluate masonry structures, further research on DEM tools and
methodologies is essential for further advancement. Computational
Modeling of Masonry Structures Using the Discrete Element Method
explores the latest digital solutions for the analysis and modeling
of brick, stone, concrete, granite, limestone, and glass block
structures. Focusing on critical research on mathematical and
computational methods for masonry analysis, this publication is a
pivotal reference source for scholars, engineers, consultants, and
graduate-level engineering students.
This volume provides the latest developments in the field of steel
and composite for engineering applications, as presented at the
International Conference on Steel and Composite for Engineering
Structures (ICSCES), held in Ancona, Italy on September 12-13,
2022. It covers interest topics like control and vibration, damage
in composite materials, fracture and damage mechanics, construction
management, damage tolerance, safety, security, and reliability,
big data analytics, topology optimization and artificial
intelligence, mechanical and material engineering, structural
health monitoring, computer-aided design and manufacturing, crack
initiation and propagation, performance and optimization,
computational fracture mechanics, inverse problem, non-destructive
testing, signal processing, artificial intelligence. It serves as a
reference work for professionals and students in the areas of civil
engineering, applied natural sciences and engineering management.
Numerical Modeling of Masonry and Historical Structures: From
Theory to Application provides detailed information on the
theoretical background and practical guidelines for numerical
modeling of unreinforced and reinforced (strengthened) masonry and
historical structures. The book consists of four main sections,
covering seismic vulnerability analysis of masonry and historical
structures, numerical modeling of unreinforced masonry, numerical
modeling of FRP-strengthened masonry, and numerical modeling of
TRM-strengthened masonry. Each section reflects the theoretical
background and current state-of-the art, providing practical
guidelines for simulations and the use of input parameters.
The Thesis presents some numerical models based on homogenization
for masonry structures subjected to in- and out-of-plane loads.
Joints and bricks are assumed either linear elastic or rigid
perfectly-plastic. In the latter case, a simple optimization
problem is derived at a cell level to evaluate the macroscopic
strength domain of masonry, using both the static and the kinematic
theorem of limit analysis. A simple polynomial expansion of the
micro-stress field in a finite number of rectangular sub-domains is
proposed, suitable to obtain with a very limited computational
effort a lower bound estimation of both in- and out-of-plane
masonry failure surfaces. Strength domains so recovered are then
implemented in suitable FE limit analysis codes for the upper and
lower bound estimation of collapse loads and failure mechanisms of
entire walls. Finally, the effect of the introduction of FRP strips
as reinforcement is discussed using standard FE homogenization in
the elastic range.
