摘要
在恶劣环境下,用纤维增强复合材料(FRP)筋取代钢筋应用于混凝土结构中,正成为解决钢筋锈蚀问题的一种较为普遍的解决方案。目前已有大量FRP筋性能和FRP筋混凝土柱性能的相关研究,但是方形螺旋箍FRP筋混凝土柱的相关研究很少。提出了方形螺旋箍GFRP筋混凝土柱承载力计算公式,并用Abaqus软件对8根柱进行模拟分析,结果表明该公式的计算结果与有限元模拟值吻合较好。
In harsh environments,the replacement of steel bars with fiber-reinforced polymer(FRP)reinforcing bars in concrete structures is becoming a widely accepted solution to overcome the problem of steel corrosion.At present,there are many related researches on the performance of FRP bars and the properties of FRP reinforced concrete columns.However,there are few researches on columns reinforced with FRP-Square-Spiral stirrups.A formula for calculating the bearing capacity of concrete columns reinforced with GFRP square spiral stirrups is proposed.Using Abaqus software to simulate and analyze the 8 columns and the results show that the calculated results of the formula are in good agreement with the finite element simulation results.
