| 摘 要： | 建立29个带填充墙的10层框架结构有限元模型,研究填充墙的材料、空间布置、各层墙数量等因素对结构自振周期的影响。分析表明:填充墙材料对自振周期影响较小,而薄弱层填充墙的数量及其在楼层中的位置是影响周期的两个主要原因。根据分析,提出考虑填充墙影响的框架结构自振周期修正模型。

| Abstract: | Twenty-nine finite element models of a ten-story frame structure were set up to investigate the influences on its natural vibrating period of the filled wall.The main influential factors included the wall's material,its spatial arrangement,and its quantity in weak story.Results indicate that the performance of filled wall's materials has little influence on the frame's natural vibrating period.The quantity of filled walls in weak floor and the location of weak floor are the two main influence factors.Based on numerical analysis,the modified models for calculating the frame's natural vibrating period are presented,where the influences of filled wall are given. |
