Local Buckling Effects on the Supports of Continuous Trapezoidal Profiled Steel Sheets

Abstract

Corrugated sheet roof decking panels are more often continuous than simply supported. They are generally designed in the elastic range, to resist the maximum bending moments at the intermediate supports. A tentative plastic design must consider the differences in the behaviour of these corrugated sheet at the supports and that in the central zone of the span. While the postcritical behaviour under bending is stable (fig.la), it becomes unstable under bending and shear (fig.lb)
