摘　　要：沣东i未来独栋商业项目采用钢网壳-混凝土混合结构体系,结构主体为混凝土框架,根据建筑形态要求,外部采用落地且在楼层处与主体结构相连的单层钢网壳。基于结构体系的特殊性,采用多软件对结构进行了多遇地震下的分析对比,以确保设计的可靠性。采用结构弹性时程对结构进行了补充计算,分析了楼层结构剪力的放大规律。根据弹塑性时程分析结果及构件损伤的分布规律,对损伤严重的杆件进行了针对性加强,确保了结构“大震不倒”的抗震设防目标。The Fengdong future standalone commercial project adopts a steel net shell-concrete composite structure system,with the main structure being a concrete frame.As per the architectural form requirements,a single-layer steel net shell externally is connected with the main structure at floor level.Due to the specific nature of the structural system,multiple software tools were used to conduct analyses and comparisons under seismic conditions to ensure the reliability of the design.Supplemental calculations were carried out using structural elastic time history analysis to examine the amplification pattern of floor shear forces.Based on the results of the elastic-plastic time history analysis and the distribution pattern of component damages,targeted reinforcements were implemented on severely damaged members to ensure the seismic design goal of“withstanding major earthquakes without collapse”for the structure.
