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 西安理工大学硕士学位论文在水平地震作用下，并考虑风荷载组合，分别对“矩形柱纯框架结构” 、 “异型柱纯框架结构” 、 “异型柱框一析架结构”及“异型柱框-剪结构”等四种结构体系，通过改变结构参数，运用空间有限元方法，进行地震作用计算。系统地分析研究“结构振型” 、 “振动周期” 、 “结构侧向刚度” 、 “结构地震反应力” 、 “楼层地震剪力” 、 “结构侧向位移” 、 “层间位移角” ，以及“构件内力” 。结果表明:在等面积原则下，异型柱代换矩形柱后，结构刚度增大，侧向位移明显减小，地震反应力略有增加，框架柱轴压比最大增幅小于8 % ，结构整体抗震性能有所提高;当异型柱肢长肢厚比小于等于3 . 6时，结构有利于抗震;水平地震作用力与整体坐标夹角为0度时，结构地震作用效应较大，属结构设计的控制因素之一;异型柱框一析架结构采用“人”字斜撑，侧向刚度大于“八”字斜撑和“人一八”字混合斜撑;异型柱框一剪结构侧向刚度大、位移小，构件内力增大适中，是一种抗震性能优越的结构体系:在抗震设防烈度较高地区( 8度)和抗震不利的建筑场地( m类场地) ，采用异型柱结构体系时，应尽可能减轻结构自重，降低地震作用力;分别采用“振型分解反应谱”法和“时程分析”法进行地震作用计算，两种方法所得结果基本一致。
Instruction about first order analysis method of frames is given by most of the current textbooks on mechanics of structure , and this method is generally used by civil engineers in calculating the internal forces of the frames , however , as the first order analysis does not consider of the additional internal forces caused by the global lateral displacement of the frame , the solution given by this way is obviously not very accurate and safe 目前的结构力学教材一般只讲授框架的一阶内力分析方法，建筑结构设计人员也普遍采用一阶的分析方法对框架进行内力分析。而框架的一阶内力分析未考虑因整个框架侧移引起的内力附加值，这个结果显然是不够精确且偏于不安全的。
