【摘要】 根据基础埋置深度与楼层高度的比值对框架柱和抗震墙的计算高度进行修正,从而考虑回填土和刚性地坪对其抗侧刚度的影响。利用ABAQUS有限元软件,对不同埋深的框架柱和抗震墙有限元模型进行计算分析,找出不同基础埋深对框架柱和抗震墙抗侧刚度的影响规律,提出简单实用的框架柱和抗震墙高度修正公式,可用于有关底框结构房屋的工程设计和科学研究。更多还原

【Abstract】 This thesis put forward that revise the calculate height by the ratio of foundation embedment depth and the story height,to consider the effect of backfill soil and rigid floor on lateral stiffness of columns and shear walls. Columns and shear walls 3D FEM models were established and analyze by ABAQUS finite element software,affecting regularities of the effect of the embedment depth of foundation to lateral stiffness of columns and shear walls were put forward,simple and practical formulas to revise the height of columns and shear walls were established. These results can be used for engineering projects and research on the masonry buildings with frame and seismic-wall in first story in the future.更多还原
