平行弦封闭栈桥钢桁架的形式分析

Style analysis of steel truss in closed trestle with parallel chord

针对平行弦封闭栈桥钢桁架在实际工程设计中存在的部分惯性问题,采用数理统计、模型计算、比较分析的方法,对平行弦封闭栈桥钢桁架在应用跨度、节间调整、形式以及上下弦支撑等方面进行了分析比较,分析结果表明平行弦钢桁架在使用、安全、经济、科学等方面存在一定的改进空间。

Aiming at the habituation problems in actual engineering design of steel truss in closed trestle with parallel chord,mathematical statistics,model calculation and comparative analysis method were applied,to analyze the span,internode adjustment, structure style, upper and lower chord support, etc. Analysis results show that, there is still certain space for improvement in the application,safety,economy,science and other aspects of parallel chord steel truss.
