基于MIDAS的等效刚度法在拆桥模拟中的应用

Equivalent stiffness method used in the simulation of removing bridge based on MIDAS

针对有限元软件的局限性,介绍了基于MIDAS/CIVIL的等效刚度法在钢筋混凝土连续梁桥拆除模拟计算中的应用,阐述了箱梁截面刚度等效的原则,并通过对比分析验证了该方法具有较好的效果。

Aiming at the limitations of finite element software, equivalent stiffness method used in the simulation analysis of removing RC continuous bridge based on MIDAS/CIVIL is introduced in this paper. The principle of equivalent stiffness method for box-girder section is also elaborated. This method achieves a good effect through the comparative analysis.
