摘　　要：为了探究能否用普通混凝土的相关理论对水下不分散混凝土短柱进行抗震设计,通过力-位移混合控制加载试验对比了低周反复荷载下水下不分散混凝土短柱和普通混凝土短柱的受力性能。结果表明:水下不分散混凝土短柱的抗震性能与普通混凝土短柱接近,可以用设计普通混凝土短柱的理论进行水下不分散混凝土短柱的抗震设计。In order to discuss whether the related theory of the common concrete could be applied to the seismic design of non-dispersible underwater concrete short columns,the mechanical properties of non-dispersible underwater concrete short columns and the common concrete short columns under low cyclic reversed loading were carried out by load-displacement mixed loading control experiment.The results show that the seismic performance of non-dispersible underwater concrete short columns and the common concrete short columns are similar,so the seismic design of non-dispersible underwater concrete short columns can use the seismic theory of the common concrete short columns.
