| 摘 要： | 通过火灾环境中混凝土内的温度场试验,以及火灾高温中玻璃纤维聚合物筋(GFRP筋)的力学性能和黏结性能试验,根据不同抗火等级对不同混凝土构件所要求的耐火极限时间,给出了GFRP筋增强混凝土结构的抗火设计方法.当抗火等级要求较高时,不宜采用GFRP筋增强混凝土结构.

| Abstract: | Based on the test results of temperature field distribution inside concrete in fire,mechanical and bond behaviors of glass fiber reinforced polymer(GFRP) bars under high temperature,fire endurance time that concrtete structure requires at different fire-resistance grade,some suggestions about fire-resistance design for concrete structures reinforced with GFRP bars are proposed.When structures require higher fire-resistance grade,the GFRP bars are not suitable for reinforced concrete structures. |

| Keywords: | GFRP bar concrete structure high temperature fire-resistance design |
