摘　　要：浙江建设科技研发中心由15层的塔楼与8层的裙楼组成,主体结构为钢筋混凝土框架-剪力墙结构,楼盖形式为平衡室内净高以及建筑造价采用钢筋混凝土框架扁梁+大板结构。裙楼与主塔楼在3-8层的连接体采用强连接的方式,连接体两端设置型钢混凝土梁、柱。三层地下室由于用地限制采用两墙合一的地下连续墙围护结构。结构设计在扩初阶段根据建筑专业要求,改进了连接体方案。由底部钢桁架、上部为钢框架的结构改为每层均采用单跨型钢混凝土框架大梁,使整体结构受力性能更优。根据超限情况采取了不同软件进行计算分析,在小震、中震、大震作用下的计算结果均能满足设计要求;并制定了相应的抗震设计性能目标,设计中针对性地采取了抗震加强措施;最后对连接体楼盖进行了舒适度验算。Zhejiang Construction Science and Technology Research and Development Center consists of 15-storey tower and 8-storey podium,the main structure is reinforced concrete frame-shear wall structure,and the form of the building cover adopts reinforced concrete frame flat beam+large slab structure for balancing the indoor headroom and the cost of the building.The connecting body between podium and main tower at the 3rd to 8th floors adopts strong connection method,and the two ends of the connection body are set up with section steel concrete beams and columns.The third floor basement adopts two walls in one diaphragm wall enclosure structure due to the limitation of land use.The structural design has improved the connection scheme according to the requirements of architectural profession in preliminary expansion stage.The structure of steel joist at the bottom and steel frame at the top was changed to single-span section steel and concrete frame beams at each floor,which makes the overall structural stress performance better.According to the overlimit situation,different softwares were adopted to carry out calculation and analysis,and the calculation results can meet the design requirements under the action of small,medium and large earthquakes;the corresponding seismic design performance objectives were formulated,and the seismic strengthening measures were taken in the design;finally,the comfort calculation was carried out for the connecting body building cover.
