Die Stabilisierung biegedrillknickgefährdeter Träger durch Sandwichelemente und Trapezbleche

Adjacent members like trapezoidal sheeting or sandwich panels can reduce the problem of lateral torsional buckling of beams by providing stabilization either by shear stiffness or by torsional restraint. Both types are investigated in this thesis by tests and numerical calculations. This concerns the shear stiffness of steel sheeting diaphragms with only two edges fastened against lateral displacements of the beam compression chord and the torsional restraint of the rotation by sandwich panels.
