摘要
探讨了对钢筋混凝土梁自加载到开裂整个过程进行有限元模拟的方法,介绍了基于损伤梁单元的剩余寿命评估的原理,结合工程实例,基于ANSYS计算钢筋混凝土梁开裂后的损伤度以及剩余寿命,为既有桥梁寿命评估提供参考。
The finite element modeling method is used to stimulate the course at which a reinforced concrete beam isn＇ t loaded until it has fissures and the principle of residual life evaluation on the basis of elements of damaged beam is introduced. Based on ANSYS, the degree of .damage and residual life after the reinforced concrete beam being split are calculated with engineering examples, which gives a reference to life evaluation of the bridges in service.
