Dynamic Load-Displacement Behavior of Rc Shear Walls under Different Loading Rates: Tests and Simulations

Article Preview

As a typical structural member, the dynamic behavior of RC shear walls under seismic dynamic loads and/or strong winds is a critical topic. In recent years, with the development of test facilities and numeric techniques, efforts have been made to study the dynamic behavior of RC shear walls under dynamic loadings experimentally and numerically. But available test results on the dynamic behavior of RC shear walls are limited because of the limitation of the large-scale test facilities for dynamic tests. In this paper, test on four RC shear walls under rapid loads are conducted and a finite element model of RC shear walls through introducing the strain rate effect to the concrete damaged plasticity model in ABAQUS is established to simulate the dynamic behavior of the four specimens tested. Through comparing the simulation result with the test result, it is clear that the developed dynamic damage plastic constitutive model of concrete can be employed to simulate the nonlinear behavior of RC walls with acceptable accuracy under dynamic load.
