    西安理工大學碩士學位論文在水平地震作用下，並考慮風荷載組合，分別對「矩形柱純框架結構」 、 「異型柱純框架結構」 、 「異型柱框一析架結構」及「異型柱框-剪結構」等四種結構體系，通過改變結構參數，運用空間有限元方法，進行地震作用計算。系統地分析研究「結構振型」 、 「振動周期」 、 「結構側向剛度」 、 「結構地震反應力」 、 「樓層地震剪力」 、 「結構側向位移」 、 「層間位移角」 ，以及「構件內力」 。結果表明:在等面積原則下，異型柱代換矩形柱后，結構剛度增大，側向位移明顯減小，地震反應力略有增加，框架柱軸壓比最大增幅小於8 % ，結構整體抗震性能有所提高;當異型柱肢長肢厚比小於等於3 . 6時，結構有利於抗震;水平地震作用力與整體坐標夾角為0度時，結構地震作用效應較大，屬結構設計的控制因素之一;異型柱框一析架結構採用「人」字斜撐，側向剛度大於「八」字斜撐和「人一八」字混合斜撐;異型柱框一剪結構側向剛度大、位移小，構件內力增大適中，是一種抗震性能優越的結構體系:在抗震設防烈度較高地區（ 8度）和抗震不利的建築場地（ m類場地） ，採用異型柱結構體系時，應盡可能減輕結構自重，降低地震作用力;分別採用「振型分解反應譜」法和「時程分析」法進行地震作用計算，兩種方法所得結果基本一致。
