摘要：Six prefabricated concrete hollow slabs strengthened with different methods were tested under static loads to investigate the flexural performance and reinforcement effects. First, four slabs were exposed to IS0-834 standard fire for 1 hour, and then respectively strengthened with carbon fiber reinforced polymer (CFRP) sheets or textile reinforced mortar (TRM). Through static loading tests, the cracking load, ultimate load, failure mode of these slabs were recorded and compared. The experimental results indicated that the ultimate bearing capacity and stiffness of strengthened hollow slabs have improved greatly. The slabs strengthened by CFRP have better performance in improving the bearing capacity, while TRM reinforcement method is more effective to improve the stiffness and deformation capacity of the prefabricated hollow slabs.
