| 摘 要： | 基于弹塑性理论,对无粘结预应力混凝土结构的非线性数值分析进行了探讨,分析了结构的材料非线性,并考虑了材料的强化作用和混凝土裂缝等因素。根据无粘结预应力混凝土结构的受力特性,考虑无粘结预应力筋与混凝土的相互作用,建立了有限元计算模型,并基于ANSYS有限元分析系统,对所建立的模型进行了全过程仿真计算,从而达到考察结构性能的目的。

| Abstract: | The non-linear analysis about unbonded prestressed concrete structure was investigated.Based on the elasticity-plastic theory,non-linear properties were studied of the material,in addition,the intensifying rules and crack model were included.Based on ANSYS program according to the characteristics of the unbonded prestressed concrete structure,the finite element model about the non-linear analysis of unbonded presturessed concrete structure,and then the full course simulating calculation was done in order to uncover the secret of the unbonded prestressed concrete structure. |
