[Abstract]:The steel frame shear wall system is a new type of lateral force resistance system. In this paper, a new type of structure system is proposed, in which the semi-rigid joints are combined with the structure system, and the steel frame is used as the main structure. The joint adopts the semi-rigid connection form of top and bottom angle steel, and makes use of the cooperative work of steel frame and steel plate shear wall to provide horizontal resistance for the structure. In this study, the method of combining test with finite element analysis is adopted. Seismic simulation shaking table test and finite element analysis are used to study the seismic performance of this kind of structural system. The contents of this paper are as follows:. 1) the design and processing of the six-story semi-rigid steel frame-steel shear wall structure model used in this experiment were completed, and the related material properties test was completed. (2) through the shaking table test of earthquake simulation, 30 seismic records were applied to the test model with different site types and different earthquake amplitudes. The displacement response of the structural model during vibration was observed. The effects of site type and earthquake amplitude on the dynamic characteristics of the structure are studied. The acceleration response, the out-of-plane deformation of the steel plate shear wall and the forming and changing process of the tension band are studied. 3) the change of the natural frequency of the structural model during vibration is obtained by processing the white noise frequency of the experimental model, and the variation of the structural stiffness during the vibration process is further analyzed.
