高温(火灾)下FRP筋混凝土构件力学性能研究进展

摘要/Abstract

摘要： 钢筋锈蚀是导致钢筋混凝土结构耐久性降低的重要原因。FRP筋具有轻质、高强和耐腐蚀等优异特性,因而有望成为传统钢筋的补充材料。FRP筋混凝土构件在服役过程中会受到高温(火灾)环境的威胁,因而FRP筋及FRP筋混凝土构件在高温(火灾)作用下的力学性能是其应用于实际工程时所面临的重要课题。综述了国内外FRP筋及FRP筋混凝土构件高温力学性能的研究成果,包括FRP筋的高温力学性能、高温对FRP筋-混凝土粘结强度的影响及FRP筋混凝土构件抗火设计方法,并对相关文献的试验数据与理论成果进行了分析和总结,指出了未来需进一步研究的方向。

Abstract: Corrosion of steel bar is an important factor for durability deterioration of reinforcing concrete structure. Fiber reinforced polymer bar, which is known as high strength to weight ratio, excellent corrosion resistance reinforced material, is expected to be an alternative material of steel rebar in the future. The performance of FRP bar reinforced concrete members under elevated temperature is becoming an important issue for high frequency of building fire. This paper reviews the relevant achievements, including the impact of elevated temperature on the FRP bars′ mechanical properties, bond strength between FRP bars and concrete under elevated temperature, fire-resistance design of FRP bar reinforced concrete members. Experimental data and theoretical models are summarized and analyzed in detail. Remaining problems and key issues, which need to be resolved in future are pointed out.

Key words: FRP bar, concrete, elevated temperature
