[摘要]gad企業(yè)總部大樓采用豎筒懸掛結(jié)構(gòu)體系,以剪力墻核心筒為主要承重和抗側(cè)力結(jié)構(gòu),上部5~12層均通過屋頂鋼桁架、外圈高強鋼吊桿及樓面鋼框架系統(tǒng)懸掛于核心筒剪力墻上,從而大大縮小了周邊豎向構(gòu)件截面,同時滿足建筑4~5層無柱空間的要求。介紹了gad企業(yè)總部大樓的結(jié)構(gòu)受力特點及性能化分析過程,根據(jù)計算結(jié)果對重要部位剪力墻采取了設置鋼板、型鋼梁、型鋼柱等加強措施,并針對懸掛結(jié)構(gòu)特點采用特殊的施工方案。分析結(jié)果表明,該結(jié)構(gòu)在大震下屋頂鋼桁架和鋼吊桿能保持彈性,加強后的剪力墻也具有極好的抗震性能,可以達到預期的性能目標。

Abstract:Vertical tube suspension structural system was adopted in gad Enterprise Building, with the shear wall corewall as the main load-bearing and lateral resistant structure. The upper 5~12 stories are suspended on the shear wall of corewall through the roof steel truss, the outer high strength steel bar and floor steel frame system, thus greatly reducing the cross section of vertical members surrounding and satisfying the columnless space requirements on 4~5 stories of the building. The structure mechanical characteristics of the performance analysis process of the building were introduced. Strengthening measures of steel plates, section steel beams and section steel columns were adopted at the important parts of the shear wall according to the calculation results. And the special construction schemes were adopted according to characteristics of the suspension structure. The analysis results show that the roof steel truss and the steel bar of the structure can remain elastic under the rare earthquake, and the reinforced shear wall also has excellent seismic performance to achieve the desired performance goals.
Keywords:high-rise building; vertical tube suspension structure; performance-based seismic design; high strength steel bar; elastic-plastic analysis
