Abstract:

提出了一种工字形截面内藏双钢板的混凝土组合柱。进行了3个不同构造的按1/10缩尺的柱模型低周反复荷载试验。试件1为普通工字形截面内藏双钢板混凝土组合柱模型,原型为某工程的底部大空间结构柱,为研究抗弯性能,取剪跨比λ=2.94;试件2为底部加强型试件,采取了对试件1内藏双腹板工字钢翼缘外侧底部贴焊加强钢板的措施;试件3为加强配筋的试件,采取了对试件1截面翼缘外侧提高纵筋配筋率的措施。分析了各模型的承载力、刚度及退化过程、延性、滞回特性、耗能和破坏特征。给出了正截面承载力计算公式,计算结果与实测符合较好。研究表明:加强型工字形截面型钢混凝土柱与普通工字形截面型钢混凝土柱相比,滞回曲线饱满,承载力、延性、耗能能力显著提高。
