AITC Capacity Tables used with the permission of AITC. These capacity tables provide an estimate of the uniformily distributed load that a glulam beam can support based on beam size, span, type of load, and strength properties. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads. These tables are provided as a guideline. Specific beam designs should be review by a licensed design professional. More technical information is available from AITC at http://www.aitc-glulam.org/.
