Design of a Steel Frame with Concrete Core Tube Hybrid Structure in Zhengzhou/Li Wensheng, Pang Fei, Zhong Yi(1 Guangxi Hualan Design & Consulting Group, Nanning 530011, China)

Abstract:The structural design, which includes structural plan, seismic analysis, seismic fortification measures and related conceptual design, of a highrise building using steel frame with concrete core tube hybrid structural system is introduced. By using the right analysis software and model, proper conceptual design and appropriate detailing, the unfavorable effects caused by the different property of concrete and steel can be reduced. This paper can be used as reference for similar projects.

Keywords:steel frame with concrete core tube hybrid system; structural analysis; seismic fortification measures; steel joint
