1) circular hollow section
圆管截面
1.
Experimental research on three truss girders made with steel circular hollow sections(CHS) under static point loading at quarter span from either end is presented in this paper.
研究结果表明,弦杆钢管内填充混凝土可提高弦杆的抗压、抗弯和径向刚度,改变节点失效模式,提高节点强度和刚度;弦杆为钢管混凝土的桁梁试件与空钢管桁梁试件一样,结构破坏均是因节点失效引起的;由于弦杆管内填充混凝土提高了节点的强度和刚度,不仅受压的上弦杆而且受拉的下弦杆管内填充混凝土,都会提高圆管截面桁梁试件的整体承载力。
2) Circular hollow sections
圆钢管截面
3) circular cross-section tube with constriction
变截面圆形管道
4) circular CFRP-steel tube
圆截面CFRP-钢管
5) circular pipe with rapid-changed cross-section
剧变截面圆管
1.
A numerical computational method for the flow in porous media in the circular pipe with rapid-changed cross-section;
剧变截面圆管内渗流的数值计算方法
6) circular pipe with sudden-changed cross-section
突变截面圆管
1.
Two examples of incompressible flow in porous media in the circular pipe with sudden-changed cross-section were numerically computed by the method of semi-false transient.
本文以突变截面圆管中不可压缩渗流为算例,利用半人工瞬变方法进行数值计算,得到流体在充满多孔介质的突扩截面圆管和突缩截面圆管中流动时关于速度分布和压力分布的结果。
