chord member

Approximate method for calculating the secondary stresses considering the combined action of deck beam and chord member of truss in double-track railway bridge

双轨铁路桥桥道梁与弦杆共同作用的近似计算

With reliable connections , the thin steel plates , which are embedded in top and bottom chord member plane in a bidirectional truss , are able to bear the applied load jointly with the primary truss and then the behavior of the structure can be improved .

在双向正交桁架上、下弦平面外将薄钢板与弦杆可靠无滑移连接，可以使钢板薄膜参与结构共同受力，从而改善原有结构的性能。

Design and Research of Double Member Open Web Bridge Supported by Lower Chord Member

双肢空腹下承式人行天桥的设计与研究

A double member open web overhead pedestrian bridge supported by lower chord member has been built in Guiyang .

一座双肢空腹下承式人行天桥已在贵阳市延安西路建成使用。

However , the brace member of K-joint may meet at the chord member partially in the many structures .

然而，在实际工程中的K型节点经常会遇到支管在与主管交汇处部分搭接的情况。

Design and checking on the gusset plate connecting the web member with the chord member in staggered truss structure systems

交错桁架中弦杆与腹杆连接节点板的设计与验算

It will give selection of pipe truss string structure chord and web member provides important design basis .

对管桁结构弦腹杆选取提供了重要的设计依据。

The structure is composed of main - arch , minor - arch , chord , wed member and cross-bar .

该结构体系由正拱、反拱、腹杆、弦杆以及横向连接杆等构件组合而成的。两个交叉拱一正一反布置，并由其他杆件相连接，构成了整个结构。

By the arch rib , top chord and web member taking load together , the trussed arch structure provide the advantages of being simple in joint structure , lower internal force , higher in-plane stiffness and remarkable economic benefits , thus have a good application prospect .

其主拱圈（下弦杆）、腹杆和上弦杆共同受力，有效的减少了拱圈内力，增加了面内拱的刚度，具有节省材料、节点构造简单等优势，有良好的应用前景。

Based on comparing the actual data with the result of finite element analysis in two kinds of modeling using ANSYS , different analysis method should be used in designing the chord and the web member in the similar trusses .

进一步用ANSYS对该结构进行了两种建模形式的有限元分析，并与实测值相比较，发现在设计类似的桁架时，弦杆和腹杆应分别按不同的分析方式进行设计比较合理。

The stress level of steel truss is lower , and stress level of end chord is smaller than that of the mid-span chord and end web member .

钢桁架整体应力水平均较低，但其端部弦杆最大应力达到跨中弦杆的50%左右，不是理想的简支状态。
