Abstract:The main structure of China Pavilion of International Horticultural Exhibition 2019, Beijing, China is divided into two parts: the upper steel roof and the lower concrete structure. The key points and difficulties of the structural design of the concrete pavilion were analyzed. Due to the need of exhibition function, large space floors were locally installed in the concrete part, and the exhibition hall was required to bear the live load more than 10kN/m2. In order to meet the structural strength of large-span floor, section steel was installed in some concrete members. The results show that the stiffness, bearing capacity and ductility of concrete structure can meet the requirements of the code.
Keywords:International Horticultural Exhibition 2019, Beijing, China; China Pavilion; steel reinforced concrete; performance-based design; large-span floor
