With the help of the electronic computers, engineers employ it to figure out nearly all kinds of engineering problems ranging from astronavigation, construction, waterpower projects, ship - building and mechanical engineering etc. owing to the strong power of finite element method, one kind of software pack which based on the method is exploited and named algor feas to resolve problems on structure analysis for trusses and shells. this paper also employ algor feas software pack to analyze and compute the cableway towers, giving the accurate result on stress and displacement both in location and whole. finally, we also bring out some advice on structure improving
在此分析過程中：首先將物理模型簡化為力學模型，主要是將塔架結構按空間桿單元簡化為空間桁架結構，目的是將力學模型變換為數學模型；這一過程主要是利用autocad2000建立塔架的計算模型；再者，利用algorfeas軟體包讀入autocad建立的塔架計算模型生成初始數據卡利用計算機進行編程進行風載計算，再將計算結論整合入algorfeas產生的初始數據卡中，生成計算數據卡；接著，利用algorfeas軟體包計算塔架在不同載荷情況下的應力圖，位移圖，並且求出在不同載荷條件下的最大位移和最大應力等；然後，對塔架的穩定性進行分析；最後；根據計算結果提出改進建議。With the rapid development in chinese economy, the steel structure and thin - walled colded - formed steel structures have been widely used in building constructions. the colded - formed angle members are one of important member in steel structures and are widely used in transmission towers, trusses and bracing members by its easy connection and erection
