| For multilayer multi-span prestressed concrete structure, because its span is bigger, in the most situations the section reinforcing bars is controled by the vertical load , therefore if continues to use the earthquake resistance design method of the reinforced concrete structure not to be able to cause the structure display best earthquake resistance ability . In order to be accurate carries on the earthquake respond analysis to the multilayer multi-span pre-stressed concrete structure, we may using the static elastic-plasticity method (Push-over) to carry on the anti-side ability analysis to the structure, makes the approximate estimate to the essential unit or the important component distortion, discovered the latent disadvantage in design because of (like intensity or rigidity sudden change ), found the spot of the structure possibly to have the big distortion and appraise structure overall stable and so on .This article first elaborated the articulation mechanism and the elastic-plasticity analysis method of the concrete frame construction , and in detail introduced principle and the process of the push-over analysis ; Then has selected southeast university's earthquake resistance experiment of prestressed complex frame , then has carried on the elastic-plasticity static analysis with large-scale finite element analysis procedure SAP2000 to the experimental frame, and carries on the result and the experimental frame the contrast, proposed some design proposals, further confirm with it is feasible that the Push-over analysis method carry on the earthquake to the prestressed concrete frame construction to respond the analysis. Finally uses SAP2000 to carry on the computation analysis to the complex frame, had determined attaches cross band little beam and side columniation altogether uses the shearing force influence to the duplicate frame which the column withstands, as well as how carries on earthquake resistance analysis and so on.
