style="text-indent:25px">鋼結(jié)構(gòu)設(shè)計(jì)簡單步驟和設(shè)計(jì)思路：構(gòu)件設(shè)計(jì)。構(gòu)件的設(shè)計(jì)首先是材料的選擇。比較常用的是Q235（類似A3）和Q345（類似16Mn）。通常主結(jié)構(gòu)使用單一鋼種以便于工程管理。經(jīng)濟(jì)考慮，也可以選擇不同強(qiáng)度鋼材的組合截面。當(dāng)強(qiáng)度起控制作用時(shí)，可選擇Q345；穩(wěn)定控制時(shí)，宜使用Q235。構(gòu)件設(shè)計(jì)中，現(xiàn)行規(guī)范使用的是彈塑性的方法來驗(yàn)算截面。這和結(jié)構(gòu)內(nèi)力計(jì)算的彈性方法并不匹配。當(dāng)前的結(jié)構(gòu)軟件，都提供截面驗(yàn)算的后處理功能。由于程序技術(shù)的進(jìn)步，一些軟件可以將驗(yàn)算時(shí)不通過的構(gòu)件，從給定的截面庫里選擇加大一級(jí)。并自動(dòng)重新分析驗(yàn)算，直至通過。這是常說的截面優(yōu)化設(shè)計(jì)功能之一。它減少了結(jié)構(gòu)師的很多工作量。</p><p
