矩形钢管柱与H形梁端板对拉螺栓连接滞回性能研究

Jianzhu Gangjiegou Jinzhan, 2013
钢结构梁柱节点有多种形式,国内外学者研究多侧重在H形梁和H形柱的连接上,对于H形梁和矩形钢管柱（RHS柱）的连接研究则很少。由于矩形钢管柱是封闭截面,节点难以采用普通螺栓连接,采用对拉螺栓连接是这种节点的一种构造解决方案。基于理论模型、结合试验和有限元方法对矩形钢管柱与H形梁端板对拉螺栓连接的滞回性能进行研究,探讨该种连接形式的滞回特性。在试验滞回曲线的基础上,提出了节点的恢复力模型,该模型对钢框架的抗震设计具有较好的参考价值。

花瓣形钢管混凝土柱轴压受力机理和承载力研究

Jianzhu Gangjiegou Jinzhan
花瓣形钢管混凝土柱具有造型美观的优点，为具体研究其受力机理和承载力，定义了其截面组成，提出了截面偏移比和截面对称系数以反映花瓣形截面性质，提出在花瓣柱中设置十字形加劲肋以增强其组合效应。基于某工程中墩柱和有限元模型，研究了花瓣形钢管混凝土短柱在轴压荷载作用下的受力机理，分析了加劲肋厚度、混凝土强度、钢材强度、加劲肋开孔直径和间距等参数对轴压性能的影响，研究了加劲肋厚度与钢管壁厚的匹配关系。根据理论分析和大量有限元参数分析结果，建议了加劲肋厚度与钢管壁厚之比和钢管名义径厚比的取值范围 ...
