摘　　要：进行了 4根无粘结部分预应力高强混凝土梁及 1根长期荷载下的无粘结部分预应力高强混凝土梁试验 ,探讨了其受力变形特点。提出了反映高强混凝土特点、与现行混凝土结构设计规范衔接的部分预应力高强混凝土梁正常使用极限状态的验算方法 。In this paper,Four unbonded partially prestressed high strength concrete beams were tested and studied,At the same time,one unbonded partially prestressed high strength concrete beam under long\|term load was tested and studied.Warping character under the concentrated load was explored.Through analyzing and ascertaining, it was put forward that check method of normal use ultimate state based on joining with code GBJ10-89 in China,which provides reference and use for revising high strength concrete code and designing engineering.

关 键 词：无粘结 部分预应力 高强混凝土 梁 根限状态
