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 R & D Design Center project for the office building, the use of frame - shear wall structure system, due to its unique shape caused by the structure of more horizontal and vertical irregularities. In addition, there are still more large-span and large cantilevered structures with a maximum span of 30.5m and a maximum cantilever length of 13.2m, which is a complex overrun high-rise building structure. In view of the irregularity of the structural plane layout, the discontinuity of the vertical component and the large-span large cantilever, the effectiveness of the force transmission path is ensured for the built-in steel in the key position. The finite element analysis of the cantilever wing wall node is carried out by HYPERWORK software, GSA software for comfort checking, LS-DYNA software for rare earthquake elasto-plastic dynamic time history analysis. The results show that the structure is reliable and the structural components can meet the established performance goals and have good seismic performance.
