- All previous earthquake were indicated that steel frame structures have well resistant - seismic behavior but due to traditional resistant - lateral systems , the resistant - lateral rigidity and ductility of steel structures ca n ' t meet resistant - seismic demands
历次强烈地震表明，采用钢结构的建筑均具有良好的抗震性能。但传统的抗侧力体系不能经济合理的满足抗侧刚度和延性等抗震要求。 - 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。 - The numerical results show that the horizontal variation of response acceleration of gravity retaining wall is quite small since its lateral rigidity is large enough , the response at a given height level can be considered as the same , the maximum accelerations at different heights on the central vertical line can describe the distribution of earthquake load along the wall height in static analysis very well
数值结果显示，重力式挡土结构刚度很大，地震加速度反应在水平方向差异很小，可看作是同步的，可取中心线上各点最大加速度来描述静力法中地震作用沿高度的变化规律。在沿墙高度方向，加速度分布不是呈直线变化，比较复杂，总的变化趋势大体一致。 - The ratio of story shear rigidity as well as the equivalent lateral rigidity ratio of story above the transfer story to the story under the transfer story should be designed properly to avoid the transfer story becoming weak story , thus the shear walls and the columns in the large base will not yield before the elements above the transfer story ; ( 2 ) the translation - torsion coupled effects and the vibration in the plane should be considered in analysis of structure with large base and muti - towers
转换层的设计除应控制层剪切刚度比外，还应控制转换层上部与下部结构的等效侧向刚度比以避免薄弱层出现在框支层，保证地震作用下落地剪力墙和框支柱不先于转换层上部结构进入屈服状态；大底盘多塔楼结构的分析必须考虑平扭耦联振动和楼板平面内振动的影响。
