摘要:
为了解决配筋率、偏心距和混杂配筋面积比对混凝土柱的破坏形式、影响侧向位移和柱正截面承载力计算的问题,采用构件试验的方法,对6根钢筋与玻璃纤维增强聚合物筋混杂配筋柱进行偏压试验。试验结果表明:混杂配筋柱最终破坏形式均为混凝土压碎且承载力较高,破坏前柱内玻璃纤维增强聚合物筋保持完好;通过合理配筋,柱延性及受拉玻璃纤维增强聚合物纵筋强度能够较好发挥;试验中玻璃纤维增强聚合物纵筋与混凝土截面应变分布符合平截面假定;同荷载时,柱侧向位移随配筋率增大而减小,随混杂配筋面积比(玻璃纤维增强聚合物与钢筋面积之比)和偏心距增大而增大。依据平截面假定,建立了混杂配筋柱正截面承载力公式,计算准度较高,供设计参考。
