Experimental study on steel plate shear walls with novel plate-frame connection
Abstract The bolt connections between frame and infill steel plate in steel plate shear wall (SPSW) are relatively weak, and their deformation around the holes of steel plate or fishplate induced by tension field effect causes difficulties in replacing the damaged infill steel plates. This paper proposes a novel plate-frame connection for thin SPSWs. The proposed connection, consisting of a fishplate with large holes, steel angles with standard holes, and bolts, is able to achieve a multi-stage force transfer mechanism. Two failure criteria of the proposed connection were defined, followed with shear test of the novel connection. Three SPSW structure specimens with various thicknesses of steel plate and plate-frame connections were tested. Finite element models for SPSW structure with novel connections were developed and verified by the test results. The influence of thickness of infill steel plate on the seismic performance and connection slippage of SPSW structure was evaluated. The results show that the novel plate-frame connection is convenient to install in SPSW as the precision requirement of bolt holes in traditional connection is mitigated. The SPSW structure with the novel connection exhibits similar seismic performance as that in the traditional bolts-connected SPSW structure. With the plastic deformation of angle steel at the latter stage, the load bearing and energy dissipation capacities of SPSW structure are increased by 0.83% and 5.4% as compared with those of the SPSW with the traditional bolt connection, respectively. The multistage stress model and two-stage failure criterion can accurately predict the failure of the plate-frame connection.
Graphical abstract According to the proposed connection form, the tensile test of the novel plate-frame connection was carried out. And three quasi-static test specimens with different thickness and connections were designed and tested according to whether the infill steel plate slipped or not. The novel connection formed between the wallboard and frame is easier to disassemble and install, which improves the construction efficiency and facilitates the functional recovery of steel plate shear wall structure. Four groups of different wallboard thickness models in different stress stages are used to explore the influence of the difference of panel thickness on the seismic performance and connection slip of the structure. The multi-stage stress model and two-stage failure criterion can better predict the failure of the steel plate shear wall connection. Display Omitted
Highlights New bolted connection for thin steel plate shear walls is proposed. Two failure criteria for the new connection are defined. Quasi-static tests were performed to identify failure modes of the connection. Numerical analyses were conducted to assess the behaviour of the proposed connection.
