Changshu Hupu Bridge was taken as an example to test and evaluate the prestressed concrete bridge after fire. On the fire crack, the concrete loss, and the reinforced exposure, the bridge fire disease was observed and analyzed. Taking the determination of concrete strength, static loading testing, and finite element analysis, the carrying capacity of the bridge after fire was analyzed and evaluated. The results showed that the simply-supported hollow slab mechanics performance in seriously fired area declines obviously. %K 钢筋混凝土桥梁,火灾,混凝土强度,静动载试验
