EXPERIMENTAL STUDY ON SEISMIC BEHAVIOR OF HIGH PERFORMANCE CONCRETE SHEAR WALL WITH NEW STRATEGY OF TRANSVERSE CONFINING STIRRUPS

In order to improve the deformability of high performance concrete shear wall, a new strategy of transverse confining stirrup, which is called piecewise confining stirrups, was presented in this paper. Four specimens of high performance concrete shear wall were designed and the quasi-static test had been carried out according to performance-based seismic design theory. Then, the influence of the axial compression ratio, the amount and range of confinement reinforcement on the ductility, the capacity of energy dissipation and failure behavior was analyzed. It was shown that the confining effect of shear wall sections is improved by the new strategy of transverse confining stirrup. In addition, the amount and range of piecewise confining stirrups determined by the axial compression ratio and displacement ductility demand was demonstrated to be reasonable. The seismic behavior of high performance concrete shear walls was obviously improved and the ductility level of the specimens met the demands of design.
