火灾后钢筋混凝土简支矩形梁强度损伤程度的分析

THE ANALYSIS OF THE REDUCTION OF STRENGTH IN A SIMPLE SQUARE REINFORCED CONCRETE BEAM AFTER FIRE

对钢筋混凝土简支矩形梁进行了火烧后其承载能力降低程度的试验分析 ,同时进行了受压区混凝土经火烧后其抗压强度值降低程度的试验分析 ,得出了大多数钢筋混凝土受弯构件在火灾后经过补强加固仍可继续使用的结论。

Not only the test analysis is provided about the reduction of moment capacity in a simple square reinforced concrete beam after fire,but also the one is provided about the reduction of the compressive strength of concrete in the compression zone after fire.The conclusion is drawn that many of the bending elements still may be used only by reinforcing. \[
