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。 - A seismic shear capacity equation for ductility and non - ductility columns is proposed to amount for the reduced shear contribution of concrete as to the increasing of displacement ductility levels . 6 . the behavior of columns * transverse displacement within yield hinge regions is also discussed based on truss - arch model . 7 . the seismic shear capacity design equation of columns with various ductility levels is proposed in statistic method on the basis of test data collected from japan and china to simplify the equation resulted from truss - arch model
