摘　　要：本文根据四个试件的静力试验来说明预应力梁柱节点合理的形式，并对六个竖向预应力混凝土框架顶层边节点在低周反复荷载作用下的性能进行了试验研究。提出了预应力框架节点的设计建议。In this paper, based on the static experiments of four specimens, the rational type of columnbeam joints with vertical prestressing is illustrated. The behavior of six kinds of exterior joints at the top of frame with vertically prestressed colunms under low frequency cyclic loading have been tested and analyzed. Finally, design suggestions about prestressed exterior joints at the top of frame are put forward.
