正常使用状态下钢筋混凝土梁挠度非线性分析

摘要

从钢筋混凝土本构关系入手,基于有限元分析软件,建立钢筋混凝土梁有限元分析模型,分析计算出锈蚀段处梁的裂缝宽度及挠度,并与我国现行规范计算公式的计算结果对比,表明有限元软件模拟局部锈蚀钢筋混凝土梁挠度是可行的。%To begin with constitutive structure relationship of steel reinforced concrete, based on finite element analysis software, the paper establishes finite element analysis model of steel reinforced concrete beam, analyzes and calculates the cracking length and deflection of corrosion section, compares it with domestic calculation formula, and finally shows that is feasible to simulate partial corrosion steel reinforced concrete deflection with finite element software.
