[摘要]框架-核心筒結(jié)構(gòu)和筒中筒結(jié)構(gòu)是目前在高層和超高層建筑中應(yīng)用最為廣泛的兩種結(jié)構(gòu)體系。規(guī)范對這兩種結(jié)構(gòu)體系有不同的規(guī)定,然而兩者是否存在明確的界限,究竟外框架剛度達到什么樣的程度時框架-核心筒結(jié)構(gòu)就變成了筒中筒結(jié)構(gòu),規(guī)范并沒有給出明確的界定標(biāo)準(zhǔn)。以實際工程為背景,通過改變柱距和梁高來衡量兩種結(jié)構(gòu)體系在力學(xué)特性和設(shè)計上的差別,如傾覆力矩百分比、剪力百分比、位移角、周期等,從而建立相應(yīng)的評判標(biāo)準(zhǔn),為規(guī)范和結(jié)構(gòu)設(shè)計提供參考。

Abstract: Frame-core wall structure and tube-in-tube structure are two kinds of structural systems that are most popularly used in high-rise and super tall buildings. Different provisions exist in codes for these two kinds of structural systems. However, there is still no clear boundary in codes between these two structural systems about the critical frame stiffness values that can convert frame-core wall structure to tube-in-tube structure. Based on the practical project, the column space and beam height were changed to compare the mechanical characteristics and design method of two structural systems, including overturning moment percentage, shear force percentage, displacement angle and period. Corresponding evaluation standards were established to provide reference for the codes and structural design.
Keywords: frame-core wall; tube-in-tube; overturning moment; shear force percentage; period; displacement angle; differentiate
