基于ABAQUS有限元模型的火灾对钢筋混凝土梁性能的影响分析

摘要

The paper analyzed the influence of fire disaster to reinforced concrete girder and plastic model quantity. Through the simulation calculation of ABAQUS finite element model to reinforced concrete girder function, study its temperature-stress coupling and gets some meaningful conclusion which provided some reference for the fire prevention and the strengthening and maintenance.%本文分析了火灾对钢筋混凝土梁的强度及弹性模量的影响,通过ABAQUS对钢筋混凝土梁进行模拟计算,研究其温度-应力之间的耦合作用.得出了一些有意义的结论,为钢筋混凝土梁的防火及火灾后加固维修提供参考依据.
