［摘要］為對比不同后置夾層結(jié)構(gòu)布置體系的優(yōu)劣，通過某復(fù)式高層結(jié)構(gòu)的具體算例詳細(xì)探討了三種后置夾層布置體系對結(jié)構(gòu)整體性能的影響、對框架與核心筒剪力墻之間內(nèi)力分配的影響以及對框架內(nèi)力的影響。分析表明夾層布置體系對框架內(nèi)力影響較大，夾層樓層剛度越大，框架部分承擔(dān)的內(nèi)力也越大。提出后置夾層應(yīng)參與結(jié)構(gòu)整體分析，能較準(zhǔn)確地反映使用階段結(jié)構(gòu)中各構(gòu)件的實(shí)際受力狀況，計(jì)算結(jié)果合理、可靠。同時(shí)針對后置夾層結(jié)構(gòu)設(shè)計(jì)中可能出現(xiàn)的薄弱部位給出了幾點(diǎn)加強(qiáng)措施和建議。

Abstract： To compare the advantage and disadvantage of different post-built interlayer structure system， the influence of the three post-built interlayer layout system on structure performance， internal force distribution between outer frame and inner tube and internal force of the frame were discussed by example of a double high-rise structure. Analyse conclude that the post-built interlayer layout system have great influence on inter force of the frame， floor stiffness of interlayer is bigger， the internal force of the frame part will bear more. Proposed that post-built interlayer should be involved in the overall calculation and can accurately reflect the actual stress condition of components in using phase， at the same time the results of such a calculation are reasonable and reliable. Meanwhile several strengthening measures and suggestions were given to the design of layout system in view of the weak part.
Keywords： post-built interlayer； layout system； structure performance
