摘　　要：该文以研究外壳预制核心现浇装配整体式RC柱的抗震性能为目的,制作预制外壳、2个新型装配式RC柱和1个对比整浇柱,开展抗震性能试验;考察两类RC柱的破坏过程、破坏模式、荷载-位移滞回曲线、主筋及箍筋的应变发展特点,探讨3个RC柱的耗能及延性特点,研究表明外壳预制核心现浇装配整体式RC柱具有与整浇RC柱相同的整体性和抗震性能。研究成果可供新型装配式RC柱设计应用参考。In order to investigate the aseismic performance of fabricated integral RC columns with precast external shells and cast-in-place core concrete, in this paper, the precast shells and two new-type of fabricated assembly RC columns and one parallel RC column are fabricated, and aseismic tests of the columns are carried out. Based on the tests, the failure process and failure modes of the columns are studied. Besides, the hysteria curves of load-deflection, the strain developments of main bars and hoop steels are compared. Also the energy dissipations and aseismic performance are investigated. It can be concluded that the new-type of fabricated assembly RC columns have good integral and aseismic performances as the same as the general RC columns. The results of this paper can be referred for the design of the new-type of fabricated integral RC columns.
