| Abstract: | The control center main structure of Lanzhou subway lines 1- 5 is designed for 100- year service life and constructed in reinforced concrete frame- dual- core structure system. This paper describes the load value,selected ground motion parameters,durability and other parameters and clarifies the general structural arrangement,and uses STAWE,PMSAP,ETABS software to conduct overall calculation and comparative analysis of the main structure and complementary calculation with elastic time history analysis method. Through computational analysis,key parts of the structure are identified and appropriate seismic measures are taken accordingly. The results show that the main structure has good lateral stiffness,better seismic performance and proves an economical and applicable structural system in high- rise buildings. |
