摘要
本文以某结构设计竞赛赛题为背景,开展大跨度结构模型的优化设计研究.基于大型工程软件,采用杆件单元,计算了结构在各种工况下的内力,分析了结构的受力特点.最终该结构模型以较优的荷质比在规定时间内承受住了最大荷载为46 kg的跨中荷载,由此可见,科学合理地对大跨度结构进行优化设计有利于提高大跨度结构的稳定性和承载能力.本文的设计方法可供相关结构设计参考.
In this paper,the research on the optimization design of the long-span structural model is carried out under the background of the Structural Design competition.Based on the large--scale engineering software,the in-ternal force of the structure under various working conditions is calculated and the stress characteristics of the structure are analyzed.Finally,the model can withstand the mid--span load with the maximum load of 46 kg in the specified time with better load-mass ratio.The design method of this paper can be used for reference of related structural design.
