摘要

摘要: 建立12个带填充墙的10层框架结构有限元模型，研究不同地震波作用下填充墙的材料、空间布置、各层墙数量等因素对结构抗侧刚度的影响。分析表明:填充墙分别采用标准砖、空心砖、加气混凝土砌块时，薄弱层刚度突变的影响逐渐减小，但不宜忽略不计;某层填充墙截面面积与其相邻上层填充墙截面面积之比w45%时，应将该层视为薄弱层，实际设计过程中建议w最小取60%;在数值分析基础上，提出了考虑填充墙影响的框架结构层间抗侧刚度计算模型。

Abstract: Twelve finite element models of a ten-story frame structure were set up to investigate the influences on its horizontal stiffness of the filled wall under different seismic waves.The main influential factors included the walls material,its spatial arrangement,and its quantity in every story.Results indicate that from standard brick to hollow brick and aerated concrete block,the effect on changing stiffness of filled wears materials becomes smaller and smaller,but its influences cannot be ignored.When the cross-section ratio of first layers filled wall to next layers filled wall is smaller than 45%,the layer should be treaded as weak layer.The cross-section ratio can be equal or greater than 60% in design.Based on numerical analysis,the formulas for calculating horizontal stiffness are presented,on which the influences of filled wall are given.
