摘    要:对材料在高温下的力学性能曲线进行简化得到其简化模型,然后根据高温下的截面性质得到截面极限弯矩计算公式,运用板的塑性绞铰法求得板的极限弯矩,带入截面的计算公式中,即可求得截面的配筋。通过此法可以简单计算板在火灾下的配筋,以及通过已知配筋求板的耐火极限。

关 键 词:高温钢筋混凝土板  塑性绞线  简化抗火计算

Abstract:Based on mechanical capability of material in high temperature and the behaviors of reinforced concrete slab exposed to fire, the limit moment can be gained by using the plastic hinge line theory, and the number of steel bar can be calculated using limit moment, the fire resistance can also be figured out by the number of steel bar. This method is applicable to the analysis and calculation of simple supported reinforced concrete slab.
Keywords:fire  simple supported reinforced concrete slab  simplified calculation  plastic hinge line
