In this paper, a discrete element model for collapse simulation of RC frame structure is constructed by discretizing the structure into a few elements and spring groups. This model introduces special hysteretic models of connected springs for arbitrary loading path, and also takes into account reasonable failure criteria for springs considering coupling effect of shear and axial force. Based on the...
The structural member quality can be effectively insured in factory, but the joints of the fabricated members are weak to actual load. A new partially prefabricated laminated wall is introduced here. To investigate the seismic performance of this kind of laminated wall, the specimens with and without opening were tested under inversed cyclic loading. Simulation program was performed by the general...
Analysis of structural walls showed that the concrete model was limiting the accuracy of the simulation of the wall behavior. For an accurate and reliable prediction of the wall response, an effective and robust hysteretic constitutive model for concrete is needed. The Chang and Mander concrete model, which can accurately capture the concrete characteristics especially for the gradual gap closure...
In civil engineering, the simulation of the reinforced concrete (RC) members exhibit great challenge to the researchers and designers especially considering the influence of some details. RC shear wall is one of the main lateral resistance members in tall buildings. A further understanding of shear walls is important to the seismic design. It is gradually recognized that boundary elements make contribution...
