The trusses were modified at the bearing walls <br /> to insert new wood headers up "flush"within the trusses. In doing so, the <br /> trusses chords and web were cut and then re-attached to the new headers. <br /> The floor trusses aze 18"deep. These trusses were modifted by removing the <br /> vertical end members of the truss to instatl the LVL headers. The trusses were <br /> then reinf�rced with a double vertical 2 x 4 placed just inside the LVL h�ader <br /> and a flat 2 x 4 block on top of tEte bottom chord of the truss. In additior�to <br /> that framing a 3/0"plywood gusset was stapled to the side of the tiuss at the <br /> ends. The gussets measure 18"x 18" in size_ The trusses are also attached to <br /> the LVL header with steel strap hangers. <br /> �, At the roof,the trusses were modified in a similar manner by cutting and <br /> removing a portion of the bottom chord. The trusses were then reinforced by <br /> adding verticai 2 x 4 block to connect the bottom chords to the other truss <br /> members. The bearing points of the trusses were reinforced by adding <br /> plywood gussets to one side of the trusses and attaching the hvsses to the <br /> supporting LVL headers with face mounted metal hanger. <br /> Based on my observations and calculations I have concl�ded that the trusses, <br /> as rnodified,are structurally adequate and tivill support the required <br /> superimposed live loads and dead loads. If you have any questions please feel <br /> free to call me. <br /> Sincerely: <br /> J d K. ars n,P.E. <br /> S ctural n�ineer <br /> innesota Reg.No. 15847 <br /> Cc: Mr, Lyle Oman, City of Omno(fa�c) <br /> Mr.Tom Radke(fax) <br /> 2452761t1 <br /> jkl <br />
