摘要
根据混凝土热传导和自然环境温度变化的特点 ,讨论了混凝土构件温度分布形式、界面温度的计算方法。对框架结构中温度作用与作用效应的非线性关系的分析表明 ,混凝土开裂后内力减小 。
According to the features of thermal conduct of concrete and temperature variation of environments,the distribution and the calculating method of surface temperature of concrete are discussed.The nonlinear analysis of thermal action and its effects on concrete frames show that the internal forces of concrete are reduced after crack but the influence of thermal action on structures is still evident.
