摘要
介绍了高层建筑收缩徐变的简化分析方法,该法可以考虑加载龄期、加载速度、构件厚度、环境相对湿度以及截面配筋率对收缩徐变的影响,用该方法对一巨型框架进行收缩徐变分析,结果表明该法简单实用,可以在超高层建筑结构设计中估算收缩徐变时使用。
A simplified creep and shrinkage analysis method of tall mega-frame structures is presented. Effects of the creep and shrinkage of loading-age, loading-rate, member thickness, surroundings relative humidity, and ratio of steel area to concrete area are taken into account. Creep and shrinkage analysis of a mega-frame structure is done using this method. The results show that this method is simple and applicable in estimating creep and shrinkage in the design of tall building structures.
