Abstract:Northeast Normal University gymnasium adopts prestress space steel structural system, the roof applys structural system of intestine prestress large span penetrated weld pipe truss, through prestress cable making cable and penetrated weld pipe truss work together, so as to adjust structural mechanics performance, and improve structural statics, dynamical characteristic and the structural overall stability. Through finite element analysis, structural performance is researched based on structural intensity, elasticity deformation and structural overall stability to expatiate the connection of prestress stiffness and structural overall stability. The results can provide reference for other similar project.
Keywords:intestine prestress; penetrated weld pipe truss; elasticity; buckling; deformation; structural overall stability
