“…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 ]…”

“…Many of these models have been documented in the literature by, for example, Sinha et al (1964), Karsan and Jirsa (1969), Buyukozturk and Tesng (1984), Yankelevsky and Reinhardt (1987a), Chang and Mander (1994), Bahn and Hsu (1998), Elmorsi et al (1998), Palermo and Vecchio (2003), Mansour and Hsu (2005) and Sima et al (2008). Most refer only to the compressive cyclic behaviour of concrete and only a few consider the cyclic tension response.…”

A hysteretic stress-strain model is developed for unconfined concrete with the intention of providing efficient modelling for the structural behaviour of concrete in seismic regions. The proposed model is based on the findings of previous experimental and analytical studies. The model for concrete subjected to monotonic and cyclic loading comprises four components in compression and tension -an envelope curve (for monotonic and cyclic loading), an unloading curve, a reloading curve and a transition curve. Formulations for partial unloading and partial reloading curves are also presented. The reliability of the proposed constitutive model is investigated for a reinforced concrete member using a non-linear finite-element analysis program. Comparisons with test results showed that the proposed model provides a good fit to a wide range of experimentally established hysteresis loops.

“…The monotonic load-deformation response of the shear panels before the application of cyclic loading was predicted using the Cyclic Softened Membrane Model (CSMM) and corresponding iterative analysis procedure recently developed by Mansour and Hsu [2004a;. The model assumes that cracks are smeared throughout the reinforced concrete element and the reinforcing bars are uniformly distributed in the two orthogonal directions and t. The CSMM satisfies both compatibility and equilibrium conditions and utilises the newly developed cyclic constitutive relationships for concrete and steel bars embedded in concrete as suggested by Mansour and Hsu [2004b]. Complete details of the solution procedures can be found in Mansour and Hsu [2004b].…”

In this paper, the damage prediction of shear-dominated reinforced concrete (RC) elements subjected to reversed cyclic shear is presented using an existing damage model. The damage model is primarily based on the monotonic energy dissipating capacity of structural elements before and after the application of reversed cyclic loading. Therefore, it could be universally applicable to different types of structural members, including shear-dominated RC members. The applicability of the damage model to sheardominated RC members is assessed using the results from reversed cyclic shear load tests conducted earlier on eleven RC panels. First, the monotonic energy dissipating capacities of the panels before and after the application of reversed cyclic loading are estimated and employed in the damage model. Next, a detailed comparison between the analytically predicted damage and the observed damage from the experimental tests of the panels is performed throughout the loading history. Subsequently, the effects of two important parameters, the orientation and the percentage of reinforcement, on the damage of such shear-dominated panels are studied. The research results demonstrated that the analytically predicted damage is in reasonably good agreement with the observed damage throughout the entire loading history. Furthermore, the orientation and percentage of reinforcement is found to have considerable effect on the extent of damage.
