摘要
根据对火灾作用下钢筋混凝土梁可能破坏截面的应力、应变及内力分析的基础上,编制了火灾下钢筋混凝土梁截面极限承载力的计算程序。运用该程序对钢筋混凝土梁可能破坏截面的高温极限承载力的变化进行计算、分析,由此得出混凝土梁在火灾作用下极限承载力随时间下降变化的一般规律,可用于指导工程结构的耐火设计及火灾营救。
The internal foroes in possible destroyed section of reinforced concrete beam in fire are analyzed and the ultimate bearing capability program is compiled. The ultimate bearing capability of concrete beam in fire can be obtained by above method and program. The common decline principle of ultimate beating capability in fire is proposed to guide the anti - fire design and rescue in fire.
