摘要
在温度变化的基础上建立火灾后混凝土损伤情况的评价模型。基于试验现象与数据,形成了新建模型的损伤评价准则。引入115个混凝土试块和3个柱的试验数据,运用新损伤评价方法进行了火灾后混凝土与柱的劣化程度评估,分析结果与试验结果一致。建议将新的损伤评价模型应用于火灾后钢筋混凝土柱的损伤程度确定。
Based on the temperature variety, the post-fire dam- age evaluation system of reinforced concrete members was built. On basis of the experimental phenomena and data, a new damage evaluation rule was advised for the new model. Through introducing data of 115 concrete test blocks and 3 col- umns, the degree of deterioration of concrete and column was e valuated by the new method. The analysis showed that the re- sult of new damage evaluation method was in agreement with the experiment. It was suggested that the new model could be used to evaluate the status of reinforced concrete column after fire.
