I met with Tom, the framing contractor <br /> who explained the roof framing modifications in the upstairs bedroom to create <br /> the trayed ceiling. Per my observation and analysis, the roof fi�aming <br /> moditications utilizing new LVL beains spanning between existing girder trusses <br /> and additional 2x6 rafters to stiffen the existing roof trusses which were cut at the <br /> bottom chord for the new raised ceiling is satisfactory. In my opinion, the revised <br /> roof framing meets or exceeds the requirements of the building code for snow <br /> loads and dead loads. <br /> Two additional steel hangers are required to transfer the loads between the LVL <br /> members. At the LVL beams intersecting at the corner of the bedr�om, a steel <br /> hanger is required to support the double 14" LVL beam. If a top flange type <br /> hanger cannot be installed, four (4) 1/2" or 3/8" dia. thru bolts should be used <br /> each side of the hanger instead. At the location where the lower LVL beam must <br /> be supported by the upper LVL beam, four (4) 3x3x1/4" angles can be used as a <br /> hanger. Three (3) 3/8" or 1/2" dia. tlu-u bolts are required at the lower beam and <br /> four (4) thru bolts are required at the upper beam. <br /> End of Memo <br /> ` `,``��a�uniniunuriii���i <br /> �,;�` ��,�,D G. sT'�%,,,, <br /> ;,���,�a�•' ' � �'•.� r�� <br /> v . :� •• �O G <br /> =��'` ��fisTeR�o�'•y' <br /> = Ff;OFES'�IONAL — <br /> � "• EiJGI�dEEfi ` _ <br /> �'�,�;'• 1�?;'G�� :�: <br /> '%,,;�a',�°• . ....•.•,��,,,,: <br /> '''���%,,,��,��„�����""���\ <br /> 331 2nd Avenue North 5uitc 200 Minneapoli5,MN 55401 612-341-9372 612-339-4783 fax 5trohengineering@worldne�.Ai7.net <br />
