Buckling analysis of semi-rigid gabled frames

Abstract

It is intended to perform buckling analysis of steel gabled frames with tapered members and<br><br>flexible connections. The method is based on the exact solutions of the governing differential equations for<br><br>stability of a gabled frame with I-section elements. Corresponding buckling load and subsequently effective<br><br>length factor are obtained for practical use. For several popular frames, the influences of the shape factor,<br><br>taper ratio, span ratio, flexibility of connections and elastic rotational and translational restraints on the<br><br>critical load, and corresponding equivalent effective length coefficient are studied. Some of the outcomes are<br><br>compared against available solutions, demonstrating the accuracy, efficiency and capabilities of the<br><br>presented approach.
