Abstract
Fiber wall element model which considers cumulative damage effect of material is set up by introducing cumulative damage index to the fiber wall element hysteretic models of reinforcement and concrete. Numerical simulation analysis of cyclic loading test of short-limb shear wall is conducted based on fiber wall element model, and the corresponding pseudo-static test of short-limb shear wall is conducted. Results demonstrate that energy dissipation capacity and ductility of T-shaped short-limb shear wall are good. All the specimens failed under a flexural-dominant behavior, and the damage was mainly concentrated in the boundary element of the web. Special attention should be paid to the design of the web boundary. The model exhibits a high level of numerical stability and computational efficiency for all specimens investigated. Comparisons of experimental and analytical results demonstrate that the proposed fiber wall element model, with good accuracy, the cyclic load-displacement behavior of shear wall specimens, providing an important reference to the seismic performance assessment of RC short-limb shear wall.
