摘要

本文介绍了框筒结构中的正负剪力滞后现象与基本特点,总结了国内外学者在进行框筒结构的剪力滞后研究分析中所使用的方法原理,综述了到目前为止框筒结构剪力滞后的研究成果,揭示了水平荷载作用下框筒结构产生剪力滞后的原因以及现有研究成果中关于角柱设计理念上的冲突。并认为:现有研究中的关于楼盖面内刚度为无限大的基本假定是不合理的,只有充分考虑楼盖刚度的影响才能有效地反映结构中的正负剪力滞后现象,为结构设计提供合理与可靠的设计依据,从而能更大范围推广框筒结构在超高层建筑中的应用。
Based on investigations on the studies of shear lag in framed-tube structures in the world,the paper introduces positive and negative shear lag in framed-tube structures and its characteristics,summarizes the applied analysis methods in studying shear lag in framed-tube structures,analyzes related causes leading to the appearance of shear lag,and discovers the existing confliction in design ideas of corner columns.The paper also points out that the conmmonly-used assumption that floor infinitely rigid in its plane is unreasonable,and that taking floor flexibility in its plane into consideration is of value to effectively analyze shear lag in framed-tube structures and to extend application of framed-tube structures through supplying more reasonable and reliable analytical results to designers.
