Abstract: Base on the analysis of 50 000m3 water-sealed gasholder, a suitable reformation scheme was put forward to meet building functional requirements for exhibition center, arts center, film museum. Furthermore, the specific reformation schemes of the support structure, original vertical elements and roof were introduced in detail. According to the code, the analysis and calculation were conducted and calculation results were listed out.

Keywords: water-sealed gasholder; reformation; brace; tubular laced column; slenderness ratio; truss
