协同组合网架是近年来出现的一种保留网架上弦杆的组合网架,是一种新的结构形式。它利用网架来做面层混凝土的施工支架,缩短了工期,适于城市人行天桥等对施工有着特殊要求的建筑结构使用。提出协同组合网架的有限元计算与分析方法,利用有限元软件ANSYS对于贵阳市山水黔城2号人行天桥进行了线性与非线性分析。完成了工程计算及其数据的分析、归纳、总结。在研究过程中,分别对这个工程作整体分析比较,从宏观角度揭示该类体系的内力特征。最后提出了窄扁组合网架的一些设计建议及有待于进一步解决的问题。
Synergistic combination of the grid is a combination of grid in recent years to retain the grid chords, is a new structure. It uses the grid to do concrete construction scaffolding, shorten the construction period, suitable for urban pedestrian bridges and other construction has special requirements for the use of the building structure. The method of finite element calculation and analysis for collaborative combined grid is proposed. The finite element analysis software ANSYS is used to analyze the linear and nonlinear analysis of the pedestrian bridge of Qiancheng No.2 in Guiyang. Completed the engineering calculation and data analysis, summarized, summarized. In the course of the research, the overall analysis and comparison of this project were separately made, and the internal force characteristics of such systems were revealed from a macro perspective. Finally, some design suggestions of narrow flat grid and some problems to be solved further are put forward.
