摘要: 某高層酒店辦公樓的平面呈現(xiàn)明顯的“Z 形”,存在組合平面、扭轉(zhuǎn)不規(guī)則及躍層斜柱等不規(guī)則項,并通過大跨鋼連廊與裙房相連. 結(jié)合項目主要特點,詳細介紹了結(jié)構(gòu)設(shè)計要點,對細腰區(qū)域樓板及豎向構(gòu)件、躍層斜柱等關(guān)鍵構(gòu)件制定了相應的抗震加強措施?并通過地震作用下的整體分析計算,對結(jié)構(gòu)抗震性能進行了驗證,基于分析結(jié)果對薄弱部位進行了加強. 分析結(jié)果表明,結(jié)構(gòu)具有良好的剛度、承載力及變形耗能能力,符合規(guī)范和抗震概念設(shè)計要求.
關(guān)鍵詞: “Z 形”平面;高層建筑;躍層斜柱;抗震加強措施;專項分析

Abstract: The plane of a high-rise hotel office building presents an obvious “Z-shape”, there are irregular items such ascombined planes, torsional irregularities and jump-storey inclined columns, and the buildings are connected to the podiumthrough large-span steel corridors. Combined with the main features of the project, the main points of structural design wereintroduced in detail, and corresponding seismic strengthening measures were formulated for key components such as floorslabs in the slender waist area, vertical components, and jump-storey inclined columns. The seismic performance of thestructure was verified through the overall analysis and calculation under the action of earthquake, and the weak parts werestrengthened based on the analysis results. The analysis results show that the structure has good stiffness, bearing capacityand deformation energy dissipation capacity, which meets the requirements of specification and seismic conceptual design.
