| Abstract: | Under the conditions of the experiment, the aseismic behavior of prestressed concrete is better than that of reinforced concrete. A restoring force model of PC frame is put forward. The concept of the state of restoring force model is also put forward. And the concepts of model family, of specific model and of complete model are expounded. Furthernore the "Complete Model Identification Method" (CMIM) for the identification of nonlinear mathematical model of a structure from results of dynamic earthquake simulation test with many test runs is put forward, and the complete mathematical models of PC specimens are identified with CMIM. |
