| Plate Shear Wall Steel(SPSW), which is the main material of steel, has been widely concerned by researchers at home and abroad, but the research is mainly on the steel plate shear wall in low and middle structure., in the application of high-rise steel structure, structural vibration analysis, there are some shortcomings. Based on this background, the main content of this paper consists of the following aspects:(1) According to the research of the structure and the basic theory of the non stiffened steel plate shear wall, two simplified equivalent model of steel plate shear wall is discussed. The material, geometrical nonlinearity, numerical analysis method and seismic wave selection of frame-shear wall system in seismic analysis are studied.(2) Taking the symmetrical steel frame structure as an example, the time history response of the structure under the earthquake action of the non stiffened steel plate shear wall is analyzed by numerical method. The effect of steel plate shear wall structure on the vibration reduction effect of the two kinds of different plate thickness is studied, and it is proved that the effect of the thick plate shear wall is better. The study found : The steel plate shear wall has good effect on the structure of the frame, but the effect of the structure is different in different seismic wave types, among them: the structure under the effect of the Tianjin wave is the best, El Centro times is the second, the structure of the impact of the Taft wave damping effect is slightly worse; And for the same kind of seismic wave, the energy dissipation capacity of the same kind of seismic wave is more and more strong with the earthquake intensity.(3) Taking the eccentric steel frame as an example, the time history response of the shear wall structure with the non stiffened steel plate in earthquake is analyzed by numerical method. It can be seen that the steel plate shear wall can play a good control effect on the structure of the flat torsional vibration. However, under the influence of different seismic waves, the vibration control of structure is different, and the effect of Tianjin wave is the best, and the effect of Taft is a little worse. |
