Purpose: Assembled construction technology is widely used due to its advantages of fast construction and reliable quality. The purpose of this paper is to investigate the response and failure mode of the assembled shear wall-composite frame structure under different seismic intensity, to study the seismic performance of the structural system, and to evaluate the shear distribution model of seismic floor recommended by ASCE / SEI 7-10 The rationality. Innovative points: 1. Through the pseudo-dynamic test, the seismic performance of the assembled composite frame structure is studied. 2. The force performance when the two sides are connected to the steel plate-shear wall is analyzed. 3. The ASCE / SEI 7-10 earthquake floor shear distribution rationality. The seismic response and failure mode of fabricated steel plate shear wall-composite frame are analyzed by carrying out pseudo-dynamic experimental research under different earthquake intensity.2. By comparing the standard formula with the experimental data, it is verified that the shear distribution of seismic floor The rationality. The conclusions are as follows: 1. The shear walls connected with the steel plate on both sides buckle under a small load, resist the horizontal load and yield energy by the tension belt formed by buckling; 2. Assembled by the variable beam high- 3. The composite frame has stable mechanical properties, good energy dissipation capacity and sufficient ductility. 3. The assembled frame specimens analyzed in this paper have suffered serious cracking of the composite beams and the stress between the shear wall and the composite beams Bolt connection punching damage phenomenon should be avoided by reasonable design to avoid the failure mode; 4 Design Code ASCE / SEI 7-10 proposed formula can reasonably predict the seismic floor shear distribution.
