The semi-rigid steel frame-composite steel plate shear wall structure (SCSW) effectively improves the lateral stiffness of shear wall, making it possible to use the semi-rigid joint. In order to study the plastic failure mechanism of SCSW, a plastic model is established, in which the effects of the rotations of semi-rigid joints and yield deformations of infill steel walls on the energy consumption are considered. Based on that, a design method for the lateral ultimate strength is put forward and a nonlinear FEM model is setup using ANSYS. Through the comparison between plastic analysis results with the finite element results, it is shown that the plastic analysis method is feasible and has a safe redundancy.

Due to mechanical performances of brace and steel plate, mechanical properties of semi-rigid joints and its construction and installation, semi-rigid steel frame-braced steel plate shear wall system is proposed. Nonlinear static analysis with parameters (thickness of plate, type of brace, size of brace and the ratio of span to height) changed of a single-span and single-floor semi-rigid steel frame-braced steel plate shear wall system illustrates that braced steel plate shear walls contributes obviously to bearing capacity and lateral rigidity of semi-rigid steel frame. Also, the finite element analysis (by ANSYS) show that semi-rigid steel frame-braced steel plate shear wall system has excellent ductility.

This paper mainly researched the behavior of double fish plate connector between steel plate shear wall structure and steel frame. Four single fish plate connectors and four double fish plate connectors were tested under monotonic and cyclic loading. The hysteretic curves, skeleton curves, stiffness degradation curve and ductility coefficient were considered to study the behavior of two connections. Results showed that the behavior of double fish plate connector between steel plate shear walls and steel frame was better than single fish plate connector. Double fish plate connectors had higher bearing capacity, slower stiffness degradation, better ductility and better energy dissipation capacity. Constraint effect of steel plate shear walls became stronger, and the out-of-plane buckling failure of steel plate shear walls was delayed. Therefore, the double fish plate connectors could improve the behavior of connection between steel plate shear walls and steel frame, and provide a reference for engineering application

Mega steel braced frame-composite steel plate shear wall structure, consisting of mega steel braced frame as outer frame and composite steel plate shear walls as core wall, is a new type of hybrid structure that is proposed in this study. Seismic performance of this new structure was analyzed under frequent earthquake and severe earthquake. The analysis focused mainly on displacement response, seismic base shear distribution and failure mechanism. Comparing with traditional steel frame-RC core wall structure, this new type of hybrid structure presents better coorporative working performance since mega steel braced frame provides larger stiffness and composite steel plate shear wall provides a fairly ductile response. It can be observed from the failure mechanism that this structure has multiple seismic resistant systems with composite steel plate shear wall, mega braces and mega frame when subjected to severe earthquakes.

Composite steel plate shear wall (CSPSW), as a new lateral force resisting structure composed of steel plate and concrete slab, is introduced. CSPSWs can fully display the superiority of the steel plate and concrete. Ductility and energy dissipation capacity of the walls are increased and seismic behavior is improved. Recent seismic research around the word of two kinds of CSPSWs, namely, CSPSW with signal steel plate and CSPSW with double steel plates, is presented and discussed comprehensively. Some existing problems in current research of the walls are also reviewed in this paper.

Moment Resisting

The seismic behavior factor of moment resisting steel frame-steel plate shear wall under two different horizontal loading patterns was investigated according to the maximum inter-story drift ratio reaching 1/50. It could be achieved with the same calculated standard as the foreign codes and the determined behavior factor was compared with foreign research results. The method using the software SAP2000 to calculate seismic behavior factor according to the maximum inter-story drift ratio reaching 1/50 was presented and the specific example was used to elaborate the operating process. The seismic behavior factor R, the overstrength factor RΩ and the ductility reduction factor Rμ of 10-storey 3-span steel frame-steel plate shear wall under the inverted triangle load are respectively 6.07, 2.96 and 2.05. while they are respectively 7.2, 3.37 and 2.13 under the uniform load. Finally, it can be concluded that the economic and reasonable design goals are achieved for this structure.
