Abstract:The Exhibition Hall of Jurassic World in Lufeng is an irregular and large-span structure in highly seismic region. Steel grid-concrete frame column-concrete giant column (core tube) structure is adopted and the seismic action of integral structural is analyzed. Considering the increment of moments and axial force of column, special structural methods, such as strengthening the core tube, strengthening the connection of core tube and grid structure, adopting the rubber plinth, are applied to meet the seismic and over-length requirements.

Keywords:large-span steel grid structure; seismic action analysis; irregularity structure
