門式鋼架的受力分析ansys

1、門式鋼架的受力分析一、問題描述：門式鋼架受到均布荷載q=300N/m作用，其柱高4.5m,橫梁長12m, 柱和梁均采用鋼梁制作，楊氏模量E=3 x 10 5MPa,泊松比g=0.25, 且已知柱和梁的橫截面形式均為工字梁，其中柱的參數(shù)為1=015, W2=0.15, W3=0.3, t1=0.015, t2=0.015, t3=0.008,梁的參數(shù)為柱 的參數(shù)的1.565倍。要求：求在均布荷載q作用下門式鋼架的剪力、最大彎矩、最大轉角，繪制彎矩圖以及剪力圖。示意圖:圖1門式鋼架示意圖二、求解過程:（一）：啟動 ansys 開始所有程序ansys8.1 configure ANSYS produ

2、cts 指定工 作目錄File management給定作業(yè)名123 run。（二）：用ansys求解1、點擊 preference，選 structural，然后點 OK.2、設定單元類型：打開preprocessor下拉菜單中的Element type， 分別添加beam類型中的2 node 188與3 node 189。之后再點擊 close。AHSYS Toolbarsave_db| resum_db| quit| powrgrph|Mooney-Rivlm2D elastic3plastic23tapered543D finite straind| gI a| & d| t ml -
