Stiffeners are secondary plates or sections which are attached to beam webs or flanges to stiffen them against out of plane deformations. This drop list allows you to select the Detail without having to use the selection options from the Detail button. Stiffeners are used to prevent web buckling at supports or concentrated loads. The connection to the bottom flange is normally the most heavily loaded part of the stiffener. A Leader’s Guide for Using Cloud-Based Product Development Tools to Drive Teamwork and Innovation. Web Stiffeners are short pieces of wood (typically OSB) that fit between the web and flange.
