［摘要］超高層強(qiáng)外框(筒)結(jié)構(gòu)是一種加強(qiáng)外框而弱化內(nèi)筒或只有內(nèi)框的新型結(jié)構(gòu)體系，為研究其風(fēng)致響應(yīng)對(duì)結(jié)構(gòu)外框(筒)和內(nèi)框(筒)構(gòu)件的敏感性，以該結(jié)構(gòu)體系為分析對(duì)象，針對(duì)強(qiáng)外框(筒)結(jié)構(gòu)所涉及的結(jié)構(gòu)構(gòu)件類型，運(yùn)用基于虛功原理和功能轉(zhuǎn)換關(guān)系建立的結(jié)構(gòu)自振周期和風(fēng)致響應(yīng)顯式表達(dá)式，推導(dǎo)了響應(yīng)和周期關(guān)于構(gòu)件截面尺寸參數(shù)的靈敏度計(jì)算公式。將該靈敏度計(jì)算方法應(yīng)用于強(qiáng)外框(筒)體系的案例分析，結(jié)果表明：該方法計(jì)算結(jié)構(gòu)固有周期和風(fēng)致響應(yīng)靈敏度的精度較高；結(jié)構(gòu)自振周期、頂部位移和層間位移角對(duì)外框(筒)構(gòu)件截面參數(shù)較為敏感，驗(yàn)證了強(qiáng)外框(筒)體系設(shè)計(jì)思想的合理性。

Abstract:Super high-rise strong outer frame tube structure is a new structural system with strengthened outer frame tube and weakened inner tube (or with only the inner frame inside). In order to study the sensitivity of the wind-induced response to the outer frame tube and the inner frame tube members, the structural system was taken as the analysis object, aiming at the types of structural members involved in the strong outer frame tube structure, the virtual work principle and the functional transformation relationship were used to establish the explicit expressions of the natural vibration period and the wind-induced response, and the sensitivity calculation formulas for response and period with respect to component section size parameters were derived. The sensitivity calculation method was applied to the case study of the strong outer frame tube system. The results show that the method′s calculation accuracy of the natural vibration period and wind-induced response sensitivity of the structure is high. The natural vibration period, top displacement and inter-story drift ratio are sensitive to the cross-section parameters of the outer frame tube members, which verifies the rationality of the design of the strong outer frame tube system.

Keywords:super high-rise building; strong outer frame tube structural system; wind-induced response; sensitivity; inter-story drift ratio; fundamental period
