| Along with the development of high-rise structures, steel plate shear wallwith a higher lateral stiffness, ultimate load capacity, good energy dissipation capacity, and many other advantages, have been studied extensively both at home and abroad. When steel framework and steel plate shear wall are used collaboratively, steel plate shear wall could compensate for the lack of lateral stiffness and excessive horizontal displacement of the steel framework, etc. Most of the connections for the beams of steel framework belong to semi-rigid connections, the overall impact of semi-rigid connections on the lateral resisting performance of steel frame-steel plate shear wall should not be ignored.Based on the study of semi-rigid connections at home and abroad, this thesis will conduct a further research on the integrity of steel frame of the semi-rigid connections through theoretical analysis and finite element analysis.As for semi-rigid connections, through the theoretical analysis of initial stiffness and ultimate carrying capacity of the top and bottom angle steel frame connections with a double web, and the finite element analysis of connection parameters on the seismic performance of the overall structure, combining the steel structure standards in our country, suggestions and methods concerning the improvement of initial stiffness ultimate carrying capacity and the overall seismic performance for this connection form are proposed.As for the steel frame-shear wall structural system, the semi-rigid beam connections is introduced into this structural system in this thesis. By comparing the lateral resisting force performance of fully rigid steel frame-steel plate shear wall structure and semi-rigid steel frames-steel plate shear wall structure, the influence of semi-rigid connections on the overall structure is obtained.Finally, a conclusion is reached by comparing the analysis results, and the relevant suggestions could serve as a reference to the design and project of related fields.
