RESEARCH ON MECHANICAL BEHAVIOR OF PRE-STRESSED CONCRETE GIRDER TRANSFER FLOOR STRUCTURE
Two transfer floor structures are established in this paper, one is used reinforce concrete transfer beam (called model 1) and the other used pre-stressed concrete transfer beam (called model 2). The two transfer beams have the same deflection under vertical load but have different height. Study and analyze the structures behavior under vertical load, frequent seismic action and rare seismic action by using finite element software SAP2000. The result from the analysis indicate that when the structure is under vertical load, the prestress can greatly reduce the KZZ5 and the prestressed transfer beams internal force, but also cause other components internal force change. Exerting per-stress has little effect to the structures lateral displacement when the structure is under frequent horizontal seismic action. At the performance point, story drift angles are smaller than the code of 1/50 limited when the structure is under rare seismic action.
