As a new structural type, the integrated house with steel mortise-tenon connection has his characteristic technical superiority such as economical cost, simple design, modular production and construction. Involving complex structure stress and many difficulties in analyzing by traditional theories and FEM software, it is hard to define and assess seismic capacity of the buildings. So this paper consigned by a company in Suzhou studied the seismic behavior of integrated buildings by structural models with full scale on shaking table. Through simulated earthquake test on a shaking table, this paper analyzed the experiment data and phenomenon. The results proves that this type of composite joint had high strength and rigidity,and the house can resist 9-magnitude earthquakes and is well suited to be deployed in earthquake stricken zones.
