( Central Research Institute of Building and Construction, MCC Group Co., Ltd., Beijing 100088, China)Abstract: This project is a double-tower high-rise structure, which is designed as steel reinforced concrete frame-reinforced concrete core. The structural analysis and design were presented, including discrimination on the regularity of the structure, selection of structural system, layout of the structure, concept design and some special seismic fortification measures. Three programs were used to analyze the dynamic behaviors of the single tower and double-tower structure, and elastic time history analysis was also done.
Keywords: double-tower structure; irregular structure; mode of vibration; period ratio; seismic design
