Abstract
At the ground floor halls with an opening or more, the forces that are transmitted through the pillars due to gravitational loads (snow, and her weight) have high values. The gravitational difference that is transmitted to the pillars increases the greater the opening between the pillars is. In this Article we analyse the pillars of halls that are articulated recessed, because they have the advantage that the joints do not transmit bending moments. In the case of halls with large openings or halls rehabilitated or strengthened, to increase the critical load of loss of stability can increase the moment of inertia of the pillars from the recessed to the articulated end. In this Article, a parametric numerical study is presented, which establishes the critical load at a pillar with a variable section, depending on the length of the area where the moment of inertia of the slat has been increased.
