摘要
南京美术馆新馆建筑外形独特,结构存在平面不规则、竖向不规则、大悬挑等超限情况。介绍了该工程采用的结构体系,设计过程中的技术难点、解决方案和采取的针对性措施,通过多种计算分析软件对结构进行了中震、大震计算,楼盖舒适度,防倒塌设计,节点有限元等专项分析。结果表明:本工程结合建筑元素所采用的组合筒体-斜柱-钢桁架混合结构具有良好的受力性能,能够达到既定的抗震性能化目标。
New Building of Nanjing Art Museum has a unique shape,and the structure has out-of-code conditions including irregularities in plan,vertical irregularities,and large cantilevers.The structural system used in the project,technical difficulties in the design process,solutions and targeted measures were introduced.Through a variety of calculation and analysis software,special analyses were conducted of the structure,such as calculations under fortification and rare earthquakes,floor comfort analysis,prevention design of progressive collapse and joint finite element analysis.The results show that the hybrid structure of composite tube-inclined column-steel truss adopted in this project combined with architectural elements has good mechanical performance and can achieve the established seismic performance targets.
