摘要
本文通过对十九个预应力混凝土管柱与桩帽连接节点的受弯试验研究,描述了连接节点的破坏形态和破坏机理,分析了连接节点受弯承载力的主要影响因素.在此基础上,探讨了连接节点受弯承载力的计算模式和计算公式,建议计算方法所得结果与试验结果吻合较好.
Based on 19 flexurai tests and study results of prestressed concrete pipe pile-pile cap connections, failure patterns and mechanism of the test specimens are described, the main factors affecting flexural capacity of the connection are analyzed. The calculation model and proposed formula for calculating flexural capacity of the connection are put forword. It is showed that there-is a good agreement between the calculated results and experimental results.
