【摘要】 为解决部分高层、超高层建筑结构弹性阶段变形验算不满足规范这一问题,对建筑结构规范中弹性阶段变形验算规定的目的、方法和限值进行了探讨。通过大量的结构分析计算,总结出了高层建筑结构受力与变形之间关系的一些规律。指出了建筑结构规范中有关弹性阶段变形验算部分的值得商榷之处,在此基础上提出了弹性阶段变形验算方法的改进建议。更多还原

【Abstract】 Reviews the six opinions about the purposes of calculations for elastic deformation:1)Ensuring stability of buildings;2)Meeting the requirement of comfort;3)Enabling the P-Δeffect to be ignored;4)Avoiding the touch of adjacent buildings;5)Ensuring the structural components to undestroyed;6)Ensuring the accessorial components to undestroyed And analyses hundreds of buildings under wind and earthquake loads using a finite element anal-ysis program,which identifies the intentions of calculation for elastic deformation,and points out that nowadays,the calculation for elastic deformation of many high-rise buildings,especially some steel high-rise buildings,cannot meet the regulations of Chinese codes and this shows that the calculation for elastic deformation should be intensively studied and unified.And concludes from the results of stress of structural members and the deformation between two adjacent floors that elastic deformation calculation should not be used to ensure structural members not to be destroyed.Because the direct relationship between the stress of structural members and the de-formation between the two adjacent floors cannot be found.And it must be pointed out that the stress of the structural members and the deformation between the two adjacent floors in flexible structures are different in their distribution.更多还原
