An efficient compound-element for potential progressive collapse analysis of steel frames with semi-rigid connections

In this paper, the formulation of a novel 1D frame compound-element for the materially and geometrically non-linear analysis of steel frames with flexible connections is outlined. The element is formulated based on the force interpolation concept and the total secant stiffness approach, and implemen...
