局部均载下RC无梁板的应力重分布分析

Redistributive Stress Analysis of RC Flat Slab under Locally Distributed Load

针对局部均载下的ＲＣ无梁板，以广义力法的弹性解为基础，提出了局部均载下ＲＣ无梁板的挠度和内力的应力重分布计算方法及其公式，并和试验结果进行了比较。结果表明，弹性计算和非线性分析的内力分布规律不同，设计中应考虑应力重分布过程。

Aiming at RC flat slab subjected to locally distributed load,the computational method ofredistributive stress analysis for RC flat slab under locally distributed lead is presented.The results arecompared with the test ones,It shows that distributive inner force by nonlinear analysis is differentfrom that by elastic analysis. The course of redistributive stress should be tak en into account indesign.
