摘要

摘要: 在对4个无粘结预应力直接装配节点试件进行试验研究的基础上，采用弯矩-曲率分析方法对4个无粘结预应力直接装配节点试件进行了弹性和弹塑性阶段的分析，建立了装配节点弯矩-曲率模型，并编制了相应的计算程序，用试验结果检验了理论分析值，证明吻合良好，为研究预应力装配结构体系在大震情况下的非线性性能，提供了合理有效的非线性曲率模型。

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.
