摘要:
为研究普通钢筋与玻璃纤维增强复合材料(GFRP)筋双层混合配筋混凝土柱的偏心受压性能,对3种双层配筋形式的混凝土柱进行了偏心受压静载试验; 对比分析了双层混合配筋混凝土柱与双层单一配筋混凝土柱的偏压破坏过程、侧向变形以及荷载-应变关系等试验结果,推导了双层混合配筋偏压混凝土柱正截面承载力计算公式。结果表明:在相同配筋率下,双层混合配筋柱极限承载力明显高于纯钢筋柱,纯GFRP筋柱极限承载力最小; 双层纯钢筋柱的侧向变形最小,纯GFRP筋柱的侧向变形最大,混合配筋柱介于二者之间; 双层混合配筋柱正截面平均应变分布仍符合平截面假定; 提出的受压承载力计算公式预测值与试验实测值吻合较好,二者比值的均值为0.98,变异系数为0.076; 研究成果可为双层混合配筋柱的实际工程应用提供一定的理论基础。
Abstract:
In order to study the eccentric compression performance of double-layer hybrid-reinforced concrete columns with ordinary steel bars and glass fiber reinforced polymer(GFRP)bars, the eccentric compression static load tests were conducted on three types of double-layer reinforced concrete columns. The comparative analysis was conducted on the eccentric compression failure process, lateral deformation, and load-strain relationship of double-layer hybrid-reinforced concrete columns and double-layer single-reinforced concrete columns, and the calculation formula for the bearing capacity of the normal section of double-layer hybrid-reinforced concrete columns was derived. The results show that under the same reinforcement ratio, the ultimate bearing capacity of double-layer hybrid-reinforced columns is significantly higher than that of pure steel-reinforced columns, and the ultimate bearing capacity of pure GFRP-reinforced columns is the smallest. The lateral deformations of the double-layer pure steel-reinforced column and the pure GFRP-reinforced column are smallest and largest respectively, and the double-layer hybrid-reinforced column is among them. The average strain distribution of the normal section of hybrid-reinforced concrete column still conforms to the plane section assumption. The predicted value of the proposed formula for calculating compression bearing capacity is in good agreement with the experiment measured value, with an average ratio of 0.98 and a coefficient of variation of 0.076. The research results can provide a certain theoretical basis for the application of double-layer hybrid-reinforced concrete in practical engineering.
