| 摘 要： | 组合空腹板架是一种新型的钢一混凝土组合结构形式,从满足楼屋盖大跨度施工起拱、降低施工难度、加快施工进度的角度考虑,得出其下弦层钢肋与钢管剪力键的连接采用高强度螺栓摩擦型连接形式较优,以及通过建立非线性规划数学模型,并借助数学软件求解验证,得出在进行连接节点设计时,可采取调整螺栓布置孔距等措施,从而获得安装简易、快速、起拱、调直顺畅的良好效果.

| Abstract: | The open-web floor structure is a new-type steel-concrete composite structure.The article,in order to satisfy large span floor's constructional cambering,reduce constructional difficulty and quicken constructional course,concludes that the frictional joint of high strength bolt,linking lower steel-rib and steel-tube shear connector,is relatively excellent.Furthermore,by means of building the mathematical model of nonlinear programming and using mathematical software to solve it,the article concludes that me... |
