中国商飞大型客机制造工程技术大楼为复杂连体结构,下部4个主体塔楼(1#～4#楼)采用框架-剪力墙体系,上部屋盖采用网架及桁架体系将下部塔楼连为一体。介绍结构体系、地基基础等设计要点的同时,重点介绍了该复杂连体结构设计中风荷载、温度作用等主要问题及解决方案。根据工程抗震超限情况,提出了抗震性能化设计目标和方法。进行了小震、中震下的整体计算和罕遇地震下的弹塑性分析,分析结果表明,针对本工程提出的性能化设计目标是合理的,结构安全性能够得到保证。
China Commercial Aircraft Large-scale passenger aircraft manufacturing engineering and technology building for the complex Siamese structure, the lower four main tower (1 # ~ 4 #) using frame - shear wall system, the upper roof truss and truss grid system will be linked to the lower part of the tower One. This paper introduces the design points of structural system, foundation and so on. At the same time, it mainly introduces the main problems and solutions of wind load, temperature and so on. According to the project seismic overrun situation, proposed seismic performance design goals and methods. The overall calculation under minor earthquakes and moderate earthquakes and the elasto-plastic analysis under rare earthquakes are carried out. The analysis results show that the performance-based design goals proposed for this project are reasonable and the structural safety can be guaranteed.
