欣贺研发设计中心项目结构设计

Structural design on Xinhe R&D Center Project

厦门欣贺研发设计中心项目为办公楼,采用框架-剪力墙结构体系,因其造型独特造成结构上较多的水平和竖向不规则。除此之外项目还存在较多的大跨度和大悬挑结构,最大跨度为30.5m,最大悬挑长度为13.2m,属于复杂的超限高层建筑结构。针对结构平面布置不规则、竖向构件不连续及大跨度大悬挑等特点,对关键位置内置型钢,保证传力路径的有效性,并采用HYPERWORK软件进行悬挑翼墙节点有限元分析,采用GSA软件进行舒适度验算,采用LS-DYNA软件进行罕遇地震弹塑性动力时程分析。结果表明,结构传力可靠,各结构构件可以满足既定的性能目标,具有良好的抗震性能。

Xiamen Xinhe RD Design Center Project is office tower with frame-shear wall structural system. There are many lateral and vertical structural irregularities due to the unique architecture shape. It is a complicated out-of-code high-rise building structure with many large-span and large-cantilever structures,the maximum span is 30. 5 m,the maximum cantilever is 13. 2 m. Considering the characteristics of irregular structural layout,discontinuous vertical components,large-span and large-cantilever components,section steel was embedded in the key positions to ensure the effectiveness of the force transmission path. Finite element analysis was carried out on joints of cantilever flange wall using HYPERWORK software. GSA software was used for comfort degree checking. LS-DYNA software was used for the elastic-plastic dynamic time-history analysis under the rare earthquake. The results show that the structural force transmission is reliable,and the structural components can meet the established performance goals and have good seismic performance.
