预应力加固混凝土受弯构件的数值模拟

Numerical simulation of concrete members in bending strengthened with pre-stress

详细介绍了预应力加固混凝土受弯构件中预应力在非线性有限元分析中的模拟方法,以预应力碳纤维布加固混凝土梁为例,采用ANSYS有限元分析软件,对其进行仿真分析,提出了升温法作为模拟对碳纤维布施加预应力的方法,并详细介绍了采用升温法的原理及具体模拟过程。

Simulative methods of pre-stress in concrete members in bending strengthened with pre-stress are introduced in detail in nonlinear finite element analysis. Simulative analysis by ANSYS software is done for the concrete beams strengthened with pre-stressed CFRP sheets. The calefacient approach qua a method of simulating exerting pre-stress to CFRP sheets has been put forward. And the theory and concretely simulative process of the calefacient approach are particularized.
