摘要: 深港開放創(chuàng)新中心由西至東跌落退臺,逐漸收進,中部形成中央庭院,中庭區(qū)域通過室內(nèi)連廊和觀光樓梯相連,兩棟塔樓分別在低區(qū) 3~ 4 層、高區(qū) 11~ 14 層通過三座跨 2 層高和一個跨 4 層高的連廊連接。 結(jié)構(gòu)存在扭轉(zhuǎn)不規(guī)則及偏心布置、凹凸不規(guī)則等 6 個不規(guī)則項,屬于高層超限結(jié)構(gòu)。 簡要介紹了項目的整體情況,重點敘述了設計關(guān)鍵點:跨地塊連廊分析、大跨轉(zhuǎn)換桁架分析、斜柱和分叉柱分析等;同時進行了小震、中震彈性、大震彈塑性分析,并對分析結(jié)果提出了針對性的加強措施。 通過基于抗震性能的分析,工程滿足“小震不壞、中震可修、大震不倒”設防目標要求,可以實現(xiàn)預期的抗震性能目標 C 級要求。

Abstract: Shenzhen-Hong Kong Open Innovation Centre fell back from west to east and gradually in, form the centralcourtyard, central atrium area is connected by an indoor corridor and a sightseeing staircase, and the two tower buildingsrespectively in low area 3 ~ 4 layers, high area 11 ~ 14 layer through three across different 2 floors and a nest of 4 floorsconnection. The structure has 6 irregularity items such as torsion irregularity and eccentricity arrangement, concave-convexirregularity etc. , which belongs to the over-limited high-rise structure. The overall situation of the project was brieflyintroduced, and the key points of the design were described with emphasis on: cross-block corridor analysis, large-spanconversion truss analysis, inclined column and bifurcated column analysis, etc. At the same time, small earthquake, mediumearthquake elasticity and large earthquake elastic-plastic analysis were carried out, and the corresponding strengtheningmeasures were proposed for the analysis results. Through the analysis based on the seismic performance, the project meets thefortification target requirements of " not bad under small earthquake, repairable under medium earthquake, not collapse underlarge earthquake" , and can achieve the expected seismic performance target class C requirements.
Keywords:Shenzhen-Hong Kong Open Innovation Centre; connected structure; out-of-code high-rise structure; cross-blockcorridor; large-span conversion truss; inclined column; bifurcated column; performance objective
