摘　　要：简要介绍了钢筋混凝土筒中筒结构的空间工作原理及空间应力分布特征 ,讨论了影响剪力滞后的几个主要因素 ,定量地分析了筒中筒结构高宽比、长宽比、角柱刚度。Space working principle and character of stress distribution of reinforced concrete tube in tube structure are introduced briefly in the paper. Effects of various parameters on shear lag are discussed. Some parameters affecting space working performance, such as ratios of height to width, length to width, stiffness of corner column and ratio of core tube to framed tube are analyzed thoroughly in the paper.
