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.

Based on the time-history analysis principle of bidirectional equivalent tension rod of steel shear wall in this paper, the theory of Incremental Dynamic Analysis (IDA) is used to investigate the real seismic behavior of steel frame-steel plate shear wall (SPSW) system under a large number of natural earthquake waves and artificial simulated earthquake waves with the gradually increased scale of seismic intensity in order to achieve the base shear-roof displacement (V-Δ) curve under each earthquake wave action. Based on the principle of unidirectional equivalent tension rod, the pushover analysis is also used to obtain the curve of base shear and roof displacement under two different loading modes of uniform distribution and inverted triangular distribution. Through the above two different methods of seismic behavior evaluation, the achieved conclusions are as follows: The most V-Δ envelope curves obtained by IDA analysis are between V-Δ envelope curves obtained by pushover analysis under these two loading modes of inverted triangular and uniform distribution. With the increase of structural storey, the effect of high order mode on seismic behavior is more and more obvious and the deviation of calculation results derived from pushover is bigger and bigger. As a result, pushover analysis is only applied to evaluate seismic performance of structure at the middle or low storey. For the pushover, the structural bearing capacity and initial stiffness is underestimated, but the structural deformation capacity is overestimated under inverted triangular loading mode, Whereas, it is the opposite situation under the uniform distribution.

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.
