Re: beam replacement of interior load bearing wallFrom: info@builderswebsource.com

CommentsGenerally, to span a 22' clear opening which is also load bearing, will require a substantial beam. Of course, the size must be computed based on a detailed load analysis of all tributary and point loads falling on the beam. This could include second floor loads, roof loads, ceiling loads, wind and seismic loads, snow loads, etc. Furthermore, this load must be transferred to the exterior foundation. Foundation and exterior wall reinforcement may be required depending on the loads involved. We urge you to consult with a state licensed structural engineer who can evaluate your as-built conditions and make specific recommendations as to the use of glulam, steel, or other engineered wood options. Depending on the depth of the beam, you may not be able to conceal it fully inside the ceiling. For example, on one recent project, a glulam was used to span a 25' foot clear opening in a garage, carring a second floor load. This beam was approximately 19" deep by 6" wide. Since the ceiling joists were 2x12's, several inches of the glulam were visible in the garage. Builders Websource.
