[摘要]裝配整體式預制混凝土結構外掛墻板節(jié)點設計的相關規(guī)范、規(guī)程滯后,給預制混凝土外掛墻板節(jié)點設計提出了很多挑戰(zhàn)。針對預制混凝土外掛墻板上承式節(jié)點設計中的核心問題進行了研究分析,提出了節(jié)點荷載及其設計組合的算法、節(jié)點各部件驗算時荷載作用點的合理取法及節(jié)點承載力具體驗算方法,并對一算例采用本文方法與有限元法進行承載力計算,對比兩種方法的計算結果來驗證本文方法的正確性,可為類似外掛墻板節(jié)點的設計與驗算提供參考。

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
