Apply Simplified Model in Concept Design of Narrow & Long High-rise Buildings/Chen Xiangrong (The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010,China)Abstract:The Zhujiang New Town E-2 block department is a 31-story high tall building, locating at the CBD of Guangzhou, with 5^th story partly fram-supported shear wall system. The size of plan of this building is 103.54m long but 23.5m wide, thus the shape is narrow and long, and the building is sensible to torsion under seismic excitation. The procedure of conceptdesign of this type of building utilizing simplified modal is introduced in details.
