We are assuming that the existing wood beam is a <br /> 6"x 12" timber, and the addition of the�w column reduces its span from 20' to two spans, one <br /> of'7' and one of 13'. With the reduced span this beam is st�l inadequate a�d w�l require one ply <br /> of gang lam 1 3/4 z 11 1/4 glued and nailed to one side. <br /> If it is found that this beam is a 4"x 12" and not a 6"x 12", add one m�re gang lam of the same <br /> size. Gang lam's should have an Fb of 3100 P.S.I. � <br /> If you aze going to use a steel adjust-a post in lieu of a standard 3" steel pipe column at the new <br /> column location,the adjust-a post must have a capacity of 10 kips. <br /> We have checked the existing W 10 x 68 beam at the first�oor and it has adequate capacity f�r . <br /> this change. � � . <br /> Sincerely yours, _ <br /> I�LLSTOFTE ASSOCIATES,INC. <br /> �`•� <br /> H.
