Under the horizontal earthquake action and wind force, aim at " the pure frame structure with rectangle columns ", " the pure frame structure with special - shaped columns ", " the frame - truss structure with special - shaped columns " and " frame - shear wall structure with special - shaped columns ", earthquake action analysis was done by the spacial finite element method through the changes structural parameter. analyzing systematically " structure vibration mode ", " vibration period ", " structure lateral rigidity ", " seismic action force ", " seismic response force ", " floor seismic shear force ", " lateral horizontal displacement of structure " and " members internal force ". results indicate : ( 1 ) based on equal area, the special - shaped columns replaced the rectangle columns, the structural lateral rigidity enlarges, the lateral displacement minishes obviously, the earthquake response increase slightly, the biggest increasing amount of frame columns axis - compress ratio is smaller than 0. 08. the whole aseismic performance of structure has improved ; ( 2 ) when the section ' s length and section ' s thickness ratio of special - shaped columns is smaller than 3. 6, the structure benefits to resist seismic action ; ( 3 ) the angle of horizontal seismic action with the whole coordinate is 0 degree, structure earthquake response is bigger, belonging to a control factor of structure aseismic design ; ( 4 ) the frame - truss structure with special - shaped columns and the " a " - brace has the biggest lateral rigidity ; ( 5 ) the frame - shear wall structure with special - shaped columns have bigger lateral rigidity and smaller displacement, members internal force enlarged just rightly, have much superiority of resisting seismic action ; ( 6 ) in the higher seismic fortification criterion region ( 8 degree of seismic fortification intensity ), aseismic disadvantageous building site ( iii type site ), adopting special - shaped columns structure system, should reduce possibly the building ' s self - weight in order to reduce the earthquake response ; ( 7 ) the response spectrum method of computing seismic response and the time - history analysis method have similar analysis result
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。
