内框架砖房具有造价低、施工简便等优点,常用于百货商店、餐厅和轻工业厂房。现行抗震设计规范中所列的地震内力计算公式,关于楼盖变形对框架地震内力的影响,是按静力变形条件确定的。本文采取空间结构力学模型,运用振型分解原理和反应谱理论,进行振动分析,并选取多种楼盖刚度、横墙间距、内外柱截面尺寸,利用电子 The inner frame brick house has the advantages of low cost, simple construction, etc., and is commonly used in department stores, restaurants, and light industrial plants. The earthquake internal force calculation formula listed in the current seismic design code, and the influence of the floor cover deformation on the internal seismic force of the frame, are determined according to the static deformation conditions. This paper adopts the spatial structural mechanics model, uses the vibration mode decomposition principle and response spectrum theory to conduct vibration analysis, and selects a variety of floor stiffness, cross-wall spacing, internal and external column cross-sectional dimensions, and uses electronic
