Equivalent Plastic Hinge Length Model for Flexure-Governed RC Shear Walls

Modelling shear-flexure interaction in equivalent frame models of slender RC walls

Experimental results for quasi-static cyclic tests on reinforced concrete (RC) walls have shown that shear deformations can constitute a significant ratio of the total deformations when the wall is loaded beyond the elastic regime. For walls, which form a stable flexural hinge at their base, the ratio of shear to flexural deformations remains approximately constant over the entire range of impo...

Modelling Shear-flexure Interaction in Equivalent Frame Models of Slender Reinforced Concrete Walls

Nonlinear FE Model for RC Shear Walls Based on Multi-layer Shell Element and Microplane Constitutive Model

Nonlinear simulations for structures under disasters have been widely focused on in recent years. However, precise modeling for the nonlinear behavior of reinforced concrete (RC) shear walls, which are the major lateral-force-resistant structural member in high-rise buildings, still has not been successfully solved. In this paper, based on the principles of composite material mechanics, a multi...

Plastic Analysis and Design of Steel Plate Shear Walls

A revised procedure for the design of steel plate shear walls is proposed. In this procedure the thickness of the infill plate is found using equations that are derived from the plastic analysis of the strip model, which is an accepted model for the representation of steel plate shear walls. Comparisons of experimentally obtained ultimate strengths of steel plate shear walls and those predicted...

Elastic-plastic analysis of R/C coupled shear walls: The equivalent stiffness ratio of the tie elements

Bar frame modelling is a popular method in coupled shear wall systems in structural design. In this process, determining the stiffness of the tie beams is important. In this study, results obtained by finite-element analysis of R/C coupled shear wall systems having several geometries in elastic-plastic space are considered. Using SPSS (Ver.5.0) statistical package program, an equivalent tie bea...
