| Abstract: | A new type of RC Shear wall with concealed bracing is proposed and systemically investigated. Firstly, twenty-two 1:3 scale low-rise specimens, four 1:3 scale mid-rise specimens and seven 1:4 scale coupled specimens are designed and the experimental research on seismic behavior under cyclic loading is carried out. Shaking table tests of two 1:8 scale models of RC shear wall structure with and without concealing bracings are carried out. Secondly, on the basis of these tests, mechanical models and seismic design methods of the shear walls are proposed. Finally, the significant effects on improving the seismic performance of structure is verified by applying the shear wall with concealed bracing in some buildings. |
