南京禄口国际机场交通中心工程结构平面狭长,抗扭刚度很弱;局部楼层层高相差极大,容易形成极弱的薄弱层;设备层存在较多转换大梁;标准层楼面有较大开洞,形成两排单跨框架结构等。针对工程结构特点,结合抗震规范要求,提出了若干适当技术措施,使主体结构具有较好的承载和变形能力;并对主体结构进行了详细的弹性和弹塑性分析,找出结构潜在薄弱环节,为工程设计提供参考;最后介绍了结构的关键部位设计。
The engineering structure of Nanjing Lukou International Airport Traffic Center is long and narrow, and the torsional stiffness is very weak. The floor height difference between local floors is very large, which makes it easy to form a weak weak layer. There are more conversion girders in the equipment layer. Hole, forming two rows of single-span frame structure. Aiming at the characteristics of engineering structure and combining with the requirements of seismic code, a number of appropriate technical measures are put forward to make the main structure have better bearing and deformation capacity. The main structure is analyzed in detail in terms of elasticity and elasto-plasticity so as to find potential weak links in the structure, Provide a reference for engineering design; finally introduce the design of the key parts of the structure.
