Abstract—The piston retaining frame is an important supporting structure in the sealing system of the one-stage gasholder. A new type retaining frame is designed with simple form and high bearing capacity. In the paper, the integral deformation of the structure, the deformation and stress of the vertical rigid frame, and the stress of the members of the circumferential bracing system are respectively obtained through the FEM static analysis. The results show that both single member and integral structure can meet the design and application requirements. It can be used in one-stage gasholder design.
