样式 刚架—斜压杆模型在密肋复合墙板 力学分析中的应用（黑二加粗） 滕晓飞1 李 慧2 杜永峰1 （楷四） (1.兰州理工大学，甘肃兰州730050；2.中国建筑科学研究院，北京100013) （宋小五） 摘要：通过对14榀不同形式的密肋复合墙板试件进行水平低周反复加载、水平单调加载以及竖向单调加载试验，研究了墙板的受力特点与破坏模式以及墙板中肋梁、肋柱与填充砌块的共同工作性能。应用刚架—斜压杆简化计算模型对影响密肋复合墙板受力特点与破坏模式的主要因素进行了研究。不同算例的分析结果表明复合墙板的剪跨比、轴压比与框格的划分形式对其受力特点具有较显著的影响；外框架、肋柱和肋梁以及填充砌块对于复合墙板的受力性能分别起不同作用。 关键词：密肋复合墙板；简化计算模型；刚架—斜压杆模型（宋小五） 中图分类号：TU375.4 文献标识码：A（黑小五加粗） 文章编号：（此编号投稿时为空） Application of the simplified mathematical model of rigid frame with diagonal strut to multi-ribbed wall slab(times new roman小四加粗) Teng Xiaofei1 Li Hui2 Huang Dingye1(times new roman五号) (1.Lanzhou University,Lanzhou 730050,China；2. China Academy of Building Research,Beijing100013,China) Abstract : 14 specimens of the multi-ribbed wall slab were tested under low-frequency cyclic lateral loading, horizontal and vertical monotonously increased loading. The mechanical properties and failure modes of the wall slab and the interactive behavior between the infilling coal ash blocks and the reinforced ribs were analyzed based on the experimental study. The simplified mathematical model of rigid frame with diagonal strut was employed to analyze the main factors which affect the mechanical properties and failure modes of the multi-ribbed wall slab. The results show that shear span ratio, axial compression ratio and the arrangement of the reinforced ribs have remarkable effect on the wall slab’s mechanical properties; and the outer frame, the reinforced ribs and the infilling coal ash blocks have different effect on the mechanical performance of the wall slab respectively.
