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γw≤45%时,应将该层视为薄弱层,实际设计过程中建议γw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。 The 12 finite element models of 10-story frame structure with infill walls were established to study the influence of different seismic waves on the lateral stiffness of the infill walls, such as material, spatial layout and the number of layers. The analysis shows that the influences of the sudden change of the stiffness of the “weak layer” gradually decrease when the filled walls are made of standard brick, hollow brick and aerated concrete block, respectively. However, they should not be neglected. The cross-sectional area of ​​one filled wall is similar to that of the adjacent upper- When the ratio of cross-sectional area γw≤45%, this layer should be regarded as the weak layer, and the minimum γw of the recommended design should be 60%; on the basis of numerical analysis, the lateral stiffness Calculate the model.
