RC框架填充墙的计算模型探讨
|
摘要
为了使建筑结构设计过程中,合理考虑填充墙的作用,总结并探讨了RC框架填充墙的计算模型。砌体填充墙计算模型主要包括斜压杆模型、匀质化连续有限元模型及精细化有限元模型。通过分析及实例验证表明,填充墙采用匀质化连续模型,墙-框截面采用界面单元模型计算,能较好地评价RC填充墙框架的性能,应用于实际工程是可行的。
In order to reasonably consider the role of infill walls in the process of structure design,this paper summarized and discussed the calculation model of masonry-infilled RC frame.The calculation models of masonry infill wall include oblique strut model,homogeneous continuous finite element macro-model,and detailed finite element micro-model.Through the analysis and the example shows that homogeneous continuous model was adopted for infill wall,and interface element was used for frame-infill interaction,which can well evaluate the performance of masonry-infilled RC frame.
