Investigation into the Elastic-Plastic Ultimate Load-Carrying Capacity of Suspen-Dome
Structural stability problem is the key problem in design of steel structural. The structural stability behavior of suspended dome is investigated by employing a computation model of the Kiewitt suspend-dome with a span of 92m. ANSYS were used in the investigation. The load-displacement path of the structure is studied by using the Newton-Raphson and arc-length method. The parameters that affect the structural elastic-plastic ultimate load-carrying capacity such as rise to span ratio, height of struts, and prestress of the cables below were analyzed. Some conclusions are drawn that improving the prestress can’t improve the ultimate load-carrying capacity and higher rise to span ratio, heights of struts can improve the ultimate load-carrying capacity.
