Abstract:The Jiangsu Garden EXPO Park Future Garden adopts the single-layer stainless steel umbrella shell structure asthe load-bearing structure, the huge acrylic as the roof and the water curtain with a depth of 100mm. The 355m longstainless steel structure is connected as a whole. According to the finite element calculation results, three constructiontemperature stress release zones were set up to release the temperature stress by post welding. And then the mirror effect ofstainless steel structure was realized through polish process. The prefabricated acrylic panels and ribs were connected toform a 21m diameter circular roof through an on-site polymerization process, and flexible silica gel strips were filledbetween each circle to release temperature deformation. The whole building were divided into several construction zones,then stainless steel structure and acrylic roof were constructed in sequence. And the leveling procedure was adopted toensure the flatness of acrylic roof.
