摘要：

Reinforced concrete column strengthened with angle steel has strong high temperature resistance. Through the quantitative analysis and testing of the high temperature collapse of concrete column, the formula design of reinforced concrete column is improved to enhance the high temperature collapse performance of concrete column. Reinforced concrete columns high temperature collapse technology strengthened by angle steel based on bilinear elastic hysteretic model is proposed and equivalent linear recursive analysis method is used to calculate the restoring force model of concrete column. Experimental results show that the method can be used to calculate the ultimate crack depth and fracture toughness reliability of concrete column and detect high temperature collapse of reinforced concrete columns. It can be effectively combined with regular field nondestructive testing and long-term strain monitoring to achieve high temperature collapse of concrete column detection.
