钢筋混凝土框架剪力墙结构的位移变形研究

地震作用下的结构整体位移变形能够反映钢筋混凝土结构的变形性能,也是各楼层结构构件的位移反应和结构薄弱层判定的依据.为了研究此种变形情况,采用Pushover分析方法,设计了4个钢筋混凝土框架剪力墙构件,比较分析了推覆结构变形与理论变形的结果.研究结果表明：对于钢筋混凝土框架剪力墙结构,在一定范围内,静力非线性分析计算的结构整体位移变形与理论计算和第一振型变形结果较为吻合,静力非线性分析计算的结构整体位移变形幅度要大于由第一振型和理论计算的结构位移变形结果.通过对比分析认为,可以通过理论公式近似计算结构的整体位移变形情况.

The Displacement Deformation of Reinforced Concrete Frame Shear-walls

The overall displacement and deformation of the structure in the earthquake can reflect the deformation properties of the reinforced concrete structure. It also provides a reliable basis for the displacement response of the specific floor and the detection of weak stories. This paper aimed to study this deformation through pushover method in the 4 reinforced concrete frame shear-walls. A comparative analysis was made between the results of pushover deformation and theorelical deformation. The findings show that for reinforced concrete frame shear-walls, tile dis- placement and deformation of theoretical formulas and the first mode is very close to tile results of pushover analy sis, and the results of pushover analysis is greater than the displacement and deformation of theoretical formulas and the first mode. This comparative analysis indicates that the theoretical formula is applicable for the approximate eal culation of deformation of the structure displacement.
