摘要
制作了2根外壳预制核心现浇装配整体式钢筋混凝土柱(以下简称RC柱)和1根现浇对比RC柱试件,进行新型装配整体式RC柱的抗弯承载力试验研究,分析比较两类RC柱的破坏过程、破坏模式、荷载-位移特性、主筋应变发展特点及开裂荷载和极限承载力。研究表明:新型装配整体式RC柱与现浇RC柱具有相同的抗弯承载力特性;基于试验研究,进一步探讨新型。装配整体式RC柱极限承载力的计算理论,为该类RC柱的设计提供参考。
Two assembled monolithic RC columns with precast external shell and cast-in-place core concrete and one cast-in-place RC column were fabricated. Their bending capacities were tested. The failure process and failure modes of the columns were studied. Besides, the load deflection relation, the strain developments of main bars were compared. Also the cracking load and ultimate capacity were investigated. It can be concluded that the new-type assembled monolithic RC columns have good flexural behavior as the same as the cast-in-place RC column. Based on the test results ,a calculation method is provided, it can be referred for the design of this kind of columns.
