Test and Bearing Capacity Calculation of a New Energy-Dissipated Precast Shear Wall

At present, most precast shear walls are implemented in accordance with the method equivalent to a cast-in-place structure, where joint is complicated, and construction difficult. According characteristics of wall structures, design “strong horizontal joints, weak vertical joints” for structure proposed. The existing was used form strong damper connect joints joints. It can reduce pouring concrete improve efficiency. Three types specimens (Rectangle shape, T L shape) were designed. Low cycle reciprocating load tests carried out under different axial compression ratios (0.1, 0.3), bearing capacity ductility studied. results show that has good mechanical properties. coefficient close or greater than three, maximum 3.62. have ductility. relative displacement 1.75 mm. All dampers yield dissipate energy, which improves seismic performance plays role connecting limbs. strain distribution law specimen section discussed, simplified calculation model given, flexural put forward.
