Abstract:
Investigation into the structure performance of a commercial building was carried out after conflagration. Through analyzing the test results of inspections, a synthetical evaluation was made of the degree of damages of the structure. The corresponding schemes of strengthening and repairing the damaged structures were proposed, including reinforcing damaged beams and columns by the method of augmented section with self-compacting concrete, replacing the damaged hollow slab by cast in site concrete slabs, forming sandwich slabs with self-compacting concrete and walls with high performance composite cement mortar laminating by mesh reinforcement. Otherwise, the strengthening flow process and technology were introduced in details. The results show that the structure after reinforcement has completely functions and can meet needs of the application. It offers reference for future researches on the structural reinforcement after conflagration.
