“…In 2005, Mansour and Hsu [12,13] developed the Cyclic Softened Membrane Model (CSMM), which was an extension of yield stress and strain of bare steel bars k 1 ratio of the average compressive stress to the peak compressive stress in the concrete struts, neglecting the tensile stress of concrete k 1c ratio of the average compressive stress to the peak compressive stress in the concrete struts, taking into account the tensile stress of concrete k 1t ratio of the average tensile stress to the peak tensile stress in the concrete struts [T (α 2 )] transformation matrix as defined by Eq. (2) [V ]…”

“…Both microscopic finite element models and macroscopic models can be used for the nonlinear analysis of wall systems. The microscopic finite element models can provide detailed local responses of walls with accuracy (Park and Klingner 1997;Okamura and Maekawa 1991;Stevens et al 1991;Feenstra and de Borst 1993;Mansour and Hsu 2005;Wong and Vecchio 2002;Palermo and Vecchio 2007;Petrangeli et al 1999;D'Ambrisi and Filippou 1999). However, it requires tremendous efforts and time for modeling and numerical computations.…”

During earthquake, reinforced concrete walls show complicated post-yield behavior varying with shear span-to-depth ratio, re-bar detail, and loading condition. In the present study, a macro-model for the nonlinear analysis of multi-story wall structures was developed. To conveniently describe the coupled flexure-compression and shear responses, a reinforced concrete wall was idealized with longitudinal and diagonal uniaxial elements. Simplified cyclic material models were used to describe the cyclic behavior of concrete and re-bars. For verification, the proposed method was applied to various existing test specimens of isolated and coupled walls. The results showed that the predictions agreed well with the test results including the load-carrying capacity, deformation capacity, and failure mode. Further the proposed model was applied to an existing wall structure tested on a shaking table. Three-dimensional nonlinear time history analyses using the proposed model were performed for the test specimen. The time history responses of the proposed method agreed with the test results including the lateral displacements and base shear.

“…Pinching is due to (i) ultrastructural kinematic hardening, called the Bauschinger effect (Lee, 1989;Yaman et al, 1990;Zhao and Lee, 2002); (ii) the size of the differential angles between the fiber/rebar direction and the principal stresses in reinforced materials (Mansour and Hsu, 2005); and (iii) the local prying effect in a connection or joint (Piraprez, 1993). Analogously, the source of pinching here is ascribed to the main ultra-structural components, collagen fibrils and apatite crystallites, and their connections.…”

“…The data refer to behavior of single osteon specimens under quasi-static cyclic torsion. Application of materials science concepts (Bauschinger effect, prying, differential angle analysis) previously applied to reinforced concrete and deterioration of reinforced concrete frames under seismic shaking (Lee, 1989;Piraprez, 1993;Mansour and Hsu, 2005), in combination with analysis by a mathematical fixed point theorem (Smart, 1974), offers a fresh approach and novel understanding for further probing of human compact bone as a biological, fiber-reinforced composite.…”
