Abstract

In this paper, the mechanical characteristics and seismic performance of the bottom frame anti-seismic wall structure are analyzed. According to the calculation formula given in the code, the calculation and analysis of the four story store house with the bottom one story frame are carried out. Under the minimum material strength specified in the code, the floor stiffness ratio, equivalent stiffness, wall and frame seismic action of the bottom story are calculated. At the same time, the type, the material strength and the restrained anti-seismic wall are calculated. The results show that the number of the seismic walls has a great influence on the effective stiffness of the bottom floor, the stiffness ratio between floors, the seismic action of the wall and the seismic action of the frame column, and the key influencing factors are determined. The conclusions are as follows: by increasing the concrete strength of the seismic wall at the bottom, the stiffness of the bottom floor is increased; the strength of the block is increased, and the seismic shear allocated to the column is reduced; the number of the seismic wall has a great influence on the seismic action of the frame column at the bottom. The influence of the stiffness ratio between layers is small; the use of reinforced concrete seismic wall can optimize the stiffness ratio between layers, reduce the number of the wall, and provide a reference for the selection of engineering reinforcement scheme.
