摘   要：裝配式混凝土建筑結構復雜，在設計梁柱墻連接節(jié)點穩(wěn)定性模型時，若未考慮鋼骨和混凝土之間 的粘結滑移情況，會導致模型模擬效果不佳。為此，基于 BIM 進行裝配式建筑混凝土梁柱墻連接節(jié)點穩(wěn)定性分析。拆分裝配式建筑構件，建立 BIM 模型構件庫，計算出各類構件的抗彎承載力和剪力參數(shù)；依據(jù)梁柱墻連接 節(jié)點上螺栓的使用情況，計算出連接節(jié)點承載力等相關參數(shù)；將 BIM 技術與Revit 軟件結合，輸入構件庫內的構 件參數(shù)以及連接節(jié)點參數(shù)，獲得各構件模型并組成為整體BIM 模型，分析裝配式建筑混凝土梁柱墻連接節(jié)點穩(wěn)定性。結果表明：建立的模型效果好，混凝土梁柱墻連接節(jié)點穩(wěn)定性模擬誤差低于 1% ,  考慮到了鋼骨和混凝土 之間的粘結滑移情況，極限荷載下模擬節(jié)點穩(wěn)定的性能得到了提高，增加了穩(wěn)定性。

Abstract: The structure of prefabricated concrete buildings is complex, and when designing the stability model of beam column wall connection nodes, the bond slip between steel and concrete was not considered, resulting in poor simulation performance of the model. For this purpose, stability analysis of prefabricated concrete beam column wall connection nodes is carried out based on BIM models. Split prefabricated building components, establish a BIM model component library, and calculate the bending capacity and shear parameters of various components. Based on the usage of bolts on the connection nodes of beams, columns, and walls, calculate the relevant parameters such as the bearing capacity of the connection nodes. Combining BIM technology with Revit software, inputting component parameters and connection node parameters from the component library, obtaining various component models and assembling them into an overall BIM model, analyzing the stability of concrete beam column wall connection nodes in prefabricated buildings. The results show that the model established in this article has good performance, with a simulation error of less than 1% for the stability of concrete beam column wall connection nodes.Considering the bond slip between steel and concrete,the stability performance of the simulated nodes under ultimate load has been improved,thereby enhancing stability.

Keywords: prefabricated construction; concrete; connect nodes; stability; BIM model
