This paper studies the seismic behaviours of frame-support shear wall under cyclic loading. Two specimens were created for detailed analysis. One of the specimen was a frame-support shear wall reinforced by carbon fibre reinforced plastic (CFRP) bars, and the other by steel bars. Based on an experimental study of three frame- support shear walls, the finite-element analysis software OpenSees was adopted to conduct further theoretical research. Based on the fibre beam column model, the Pinching4 material and zero-length rotational spring were applied, and a numerical analysis model was established to analyse the walls, considering the bond slip of longitudinal reinforcement. It was shown that the numerical model considering the bond slip properly simulated the hysteresis curves of the specimens under cyclic loading, including the pinch effect. The model also achieved a good accuracy in the simulation of the yield load and ultimate load. |
