Experimental study on seismic behaviour of fully bolted concrete shear walls

art. no. e142

Bolted precast concrete shear wall structures have the potential to be disassembled and exhibit superior seismic performance. In this study, a new type of fully bolted concrete shear wall was proposed, and its seismic behaviour was examined through cyclic loading tests. The influence of the connecting method, axial compression ratio, and interface roughness on the seismic behaviour of this fully bolted concrete shear wall was analysed, and the design method was proposed. The results showed that at the axial compression ratio of 0.05, the proposed new type of fully bolted concrete shear wall structure behaved favourable seismic performance and the energy dissipation capacity was improved about 26%. Moreover, the proposed formulas used for the calculation of the bearing capacity of this connection provide a basis for the application of the fully bolted concrete shear walls.
