Beams used in heavy timber construction are sometimes firecut. this is done to: a) allow air circulation at the beam’s end in an effort to reduce moisture decay. b) counteract wind uplift forces. c) allow the beam to rotate out of the wall if it burns through. d) to ensure that columns will not buckle in the event of a fire. e) to combat the effects of wood shrinkage.
