Jianzhu Gangjiegou Jinzhan为得到带悬臂的张弦梁拉索-支座复杂节点在不同工况下的力学性能变化规律，以及在设计荷载组合下的破坏模式，结合某大跨度张弦梁实际工程，通过建立多尺度有限元模型以及现场试验的方法研究了该节点在张拉过程中的应力、应变分布特征；通过局部节点有限元分析得到了节点的极限承载能力及破坏模式；并针对其受力特征对节点构造及壁厚进行优化。结果表明在施工及使用阶段，该节点应力均处于弹性范围内，满足力学性能要求；节点的破坏荷载约为设计荷载组合的3.2倍，破坏模式为耳板上拉索孔区域受拉破坏；优化后节点的应力分布更加均匀且合理 ...

Jianzhu Gangjiegou Jinzhan在巨型结构体系的基础上提出巨型钢框架-双钢板组合剪力墙住宅体系。基于实际超高层混凝土住宅工程背景建立高度为156 m的计算模型，对其进行弹性反应分析及弹塑性时程分析以评估结构力学性能。通过对比主次结构不同的连接假定，探究主次结构连接方式对于结构整体性能及关键结构构件的影响。基于ABAQUS软件分析了次结构与双钢板组合剪力墙之间采用不同连接方式对剪力墙各部件的影响。最后对该结构体系进行经济性分析。研究结果表明：该结构体系能满足建筑户型无柱大空间设计要求且具有优良的力学性能和经济性指标，在设计中主 ...
