电站钢结构中美规范耐火极限要求对比研究

Research on Fire Resistance Rating Requirements in Chinese and American Codes While Designing Power-generation Steel Structures

对中美规范在钢结构耐火极限要求方面的内容进行了归纳,总结了按照中国规范和美国规范设计电站钢结构时的耐火极限具体要求。针对海外电站总承包项目的具体情况,在满足安全适用的前提下,结合进行总承包工程成本控制的目标,对海外电站项目中各类钢结构建(构)筑物的耐火极限设计提出了建议。

While designing power-generation steel structures,different rules should be followed using Chinese and American design codes. Fire resistance rating requirements in Chinese and American codes are listed and compared in details. As to oversea EPC projects,this issue comes with more complicated situation. To ensure safety of steel structures,higher requirements of fire resistance rating need to be executed. However,to reduce the building cost of EPC projects,adopting lower requirements seems more beneficial.Balance should be made between safety and economization. In the end,advises are given on fire resistance design of power-generation steel structures in oversea EPC projects.
