Monotonic and Cyclic Simulation of Screw-Fastened Connections for Cold-Formed Steel Framing
… an approach for modeling the monotonic and cyclic response of cold-formed steel framing screw-fastened connections in commercial finite element programs. The model proposed and verified herein lays the groundwork for seismic modeling of cold-formed steel (CFS) framing including shear …

Performance of RC Bridge Columns under Cyclic Combined Loading including Torsion
… (RC) bridge columns, specifically in the skewed and horizontally curved bridges, the bridges with unequal spans or column heights, and the bridges with outrigger bents, can be subjected to cyclic combined loading including axial, flexure, shear, and torsion loads during earthquakes. This combined …

Probabilistic capacity and seismic demand models and fragility estimates for reinforced concrete buildings based on three-dimensional analyses
… fragility estimates are conducted using the demand and capacity models typically for the 3D responses. The demand models expressed in terms of drift are developed as functions of the spectral accelerations in the two planar directions. The demand prediction is compared in a probabilistic …

Micromechanics-based approach to predict strength and stiffness of composite materials
… concerning the durability of composites is the strength and stiffness degradation during service. Traditionally, these materials have been analyzed by methods which do not take into account variations in the material at the fiber/matrix level. In addition, manufacturing techniques have advanced …

Nonlinear Truss Analysis of Non-ductile Reinforced Concrete Frames with Unreinforced Masonry Infills
Non-ductile Reinforced Concrete Frames (RCF) with and without Unreinforced Masonry (URM) infills can be found in many places around the world including the Western United States, Eastern Europe, Asia and Latin America. These structures can have an unsatisfactory seismic performance which may even …

Elastic properties and failure behavior of disordered porous solids : a potential-of-mean-force-based lattice element approach
… materials not only depend on the volume fraction and chemical composition of their constituents but also on details of their local texture. Yet, most homogenization methods do not take this texture effect into account. Understanding how local texture affects the overall elastic and failure …
