Abstract:Supporting commerce of International Horticultural Exhibition 2019,  Beijing, China contains 10 plots with buildings of 1~3 stories and maximum structural height of 14-3m. These multi-story buildings adopt RC frame structural system. Combining with the architectural characteristics of each building in the architectural scheme, three representative structural buildings were selected, and the main design situations of the structures were introduced in turn. Different structural design measures were adopted according to different structural characteristics. The design results show that the irregularity of the original structure is effectively controlled by choosing reasonable design measures. The calculation indexes of the structure can better meet the requirements of the code. The structure is safe and reliable, and the structure design is feasible.

Keywords:International Horticultural Exhibition 2019, Beijing, China; frame structure; anti-floating design; weak connection; gable roof
