| 摘 要： | 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。桥的结构新颖,造型美观,桥的栏杆与桥架共同受力,节约钢材,造价低廉,能以较小的桁架高度跨越较大的跨距,为国内首创的一种新型结构天桥。文内全面介绍它的结构构造与设计计算原理,并以该桥作为工程实例,讨论此种新结构的计算方法。

| Abstract: | A double member open web overhead pedestrian bridge supported by lower chord member has been built in Guiyang.Its structure is new and it is beautifully shaped.Because the railing and structure of this bridge are designed as a whole,the steel consumption is economized, and the construction costs are very cheap.This bridge is an initiative construction in the country. The structural construction and its calculation principle are discu- ssed in this paper,and the algorithm is discussed as a real example of this new type of structure. |
