［摘要］装配整体式预制混凝土结构外挂墙板节点设计的相关规范、规程滞后，给预制混凝土外挂墙板节点设计提出了很多挑战。针对预制混凝土外挂墙板上承式节点设计中的核心问题进行了研究分析，提出了节点荷载及其设计组合的算法、节点各部件验算时荷载作用点的合理取法及节点承载力具体验算方法，并对一算例采用本文方法与有限元法进行承载力计算，对比两种方法的计算结果来验证本文方法的正确性，可为类似外挂墙板节点的设计与验算提供参考。

Abstract: The related codes and standards for the joint design of the assembled monolithic precast concrete wall panels are lagging behind, which raises some challenges for the joint design of the precast concrete wall panels. The core problems in the process of upper load-bearing joint design of the precast concrete wall panels were studied, the load calculation method and the design combination for the joint were put forward, as well as the reasonable load point selection and the detailed capacity check method for each component check. Moreover, the bearing capacity was calculated by using calculation method discussed in this paper and finite element method respectively via a specific example. Comparing with the results of two methods, the validity of the method shown in this paper was verified, which provides a beneficial reference for similar designs.

Keywords: precast concrete; wall panel; upper load-bearing joint; finite element method
