Conceptual Design and Optimization of Roof of Steel Structure in Gymnasium

DingJiemin,Zhang Zheng(Architecture Design & Research Institute of Tongji University,Shanghai 200092,China)

Abstract:Various structural systems are applied in the large-span roof structure of Gyms,among which the hybrid tension structure is extraordinary popular for its excellent load-bearing performance as well as great adaptive ability to architectural form. It first introduces the structural types commonly used in large-span roof structure and give a survey in China these years. Then the conceptual design,elastic and plastic structural analysis and structural optimization are discussed through several cases,hoping to provide reference to the similar projects.

Keywords:structural conceptual design; elastic and plastic structural analysis; hybrid tension structure; steel roof
