Abstract

Abstract

On the basis of test researching on four unbonded prestressed assembly specimens,it was used the tool of moment-curvature to analyse the performances on elastic and elastic-plastic phase of the four unbonded prestressed precast samples.It was gained the moment-curvature model of prestressed precast specimens,by which the validity of theoretical analysis was verified by comparing the test results.Computing programmed was made and the theoretical results showed a good agreement with those of the test.Which provided a reasonable and effective nonlinear moment-curvature model for studying the non-linear performance of prestressed precast structures under a big earthquake.
