Restraint of beams by trapezoidally sheeting using different types of connection

The stability problem of lateral torsional buckling is substancially reduced by adjacent members like sheeting where stabilization by shear stiffness and by torsional restraint is present. Here the torsional restraint is investigated which is especially influenced by the type of connection. Tests were carried out for the connection by shot fired pins and under high loads. The results are given as values for the torsional restraint coefficient c(0) of the actual configuration. Account is taken of the width b(f) of the beam flange, the thickness t of the sheeting, the type of loading and the magnitude of the load A introduced from sheeting to beam.
