合肥要素大市场建筑平面开洞较多,立面开大洞并层叠出挑,多处存在大跨度及长悬挑结构。结构多项指标超限,为多重复杂高层建筑。通过设定适用于本工程的性能目标,采用基于性能的设计方法对结构进行了计算分析,采取了有针对性的抗震加强措施。分析结果表明,工程能满足“小震不坏,中震可修,大震不倒”的抗震设防目标。此外,针对工程的特殊性,对层叠出挑结构、连体结构和超长结构亦进行了详细分析和多方案比较,分析结果表明工程结构设计是安全可行的。
Hefei element big market building more openings in the plane, the facade open big hole and cascading out, there are many long-span and long cantilevered structure. A number of indicators of the structure over the limit for the multi-complex high-rise buildings. By setting the performance targets applicable to this project, the structure was calculated and analyzed by the performance-based design method, and targeted seismic strengthening measures were taken. The analysis results show that the project can meet the seismic fortification goal of “small earthquake is not bad, moderate earthquake repairable, large earthquake does not fall”. In addition, according to the particularity of the project, the detailed analysis and multi-scheme comparison on the cascading of pick-up structure, Siamese structure and over-long structure are carried out. The results of the analysis show that the engineering structure design is safe and feasible.
