【摘要】 装配式混凝土建筑结构复杂，在设计梁柱墙连接节点稳定性模型时，若未考虑钢骨和混凝土之间的粘结滑移情况，会导致模型模拟效果不佳。为此，基于BIM进行装配式建筑混凝土梁柱墙连接节点稳定性分析。拆分装配式建筑构件，建立BIM模型构件库，计算出各类构件的抗弯承载力和剪力参数；依据梁柱墙连接节点上螺栓的使用情况，计算出连接节点承载力等相关参数；将BIM技术与Revit软件结合，输入构件库内的构件参数以及连接节点参数，获得各构件模型并组成为整体BIM模型，分析装配式建筑混凝土梁柱墙连接节点稳定性。结果表明：建立的模型效果好，混凝土梁柱墙连接节点稳定性模拟误差低于1%,考虑到了钢骨和混凝土之间的粘结滑移情况，极限荷载下模拟节点稳定的性能得到了提高，增加了稳定性。更多还原

【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.更多还原
