钢筋混凝土框架结构温度作用试验及非线性分析

Experimental Study and Nonlinear Analysis of RC Frame Structure Subjected to Thermal Action

进行了小尺寸混凝土试件温度试验，拟定了钢筋混凝土框架结构温度作用试验方案．通过对此框架在温度作用及温度、机械荷载共同作用下的试验研究，观测了温度裂缝发生和发展的过程．试验结果与钢筋混凝土非线性有限元分析结果基本吻合．

An experiment of a smallscale concrete specimen subjected to thermal action is described and then an experimental program of RC frame structure subjected to thermal action is developed.The occurrence and development of temperature cracks is observed in the course of the experiment in which an RC frame model is subjected to thermal action and combination of thermal action and mechanical load.The results obtained are in agreement with the analytic results of nonlinear finite element method for reinforced concrete.
