主 题:torsional stiffness strength design elastic buckling space truss arches out-of-plane
摘 要:The out-of-plane stability of the two-hinged space truss circular arch with a rectangular section is theoretically and numerically investigated in this ***,the flexural stiffness and torsional stiffness of space truss arches are *** calculation formula of out-of-plane elastic buckling loads of the space truss arch is derived based on the classical solution of out-of-plane flexural-torsional buckling loads of the solid web ***,since the classical solution cannot be used for the calculation of the arch with a small rise-span ratio,the formula for out-of-plane elastic buckling loads of space truss arches subjected to end bending moments is *** research of the out-of-plane stability of space truss arches under different load cases shows that the theoretical formula proposed in this paper has good ***,the design formulas to predict the out-of-plane elastoplastic stability strength of space truss arches subjected to the end bending moment and radial uniform load are presented through introducing a normalized slenderness *** assuming that all components of space truss circular arches bear only axial force,the design formulas to prevent the local buckling of chord and transverse tubes are ***,the bearing capacity design equations of space truss arches are proposed under vertical uniform load.
