A local inspector raised concern over the right roof valley beam above the entry to the house. The valley beam is not continuous over its span and has been spliced in one location. KJG was provided constmction drawings for the house prepared by R.A.K. I-lame Design, and as-built dimensions of the valley beam were taken by Henry Poor Lumber Company. The existing valley beam is a 2xI2 spanning 26'-6". The splice is located approximately 6'-8" from the low end of the beam, and a 1'/s"xII'j." engineered wood rim board, 12'.-0" long, has been . cet\tered over the splice KJG was not provided any information on the attacbment between tbe rim board and 2x 12. KJG Engineering based our analysis of the valley beam on dimensions from R.A.K's drawings, as-built dimensions provided by Henry Poor, a roof dead load of 10 pounds-per-square-foot (psf},and a roof snow load of 20 psf. Based on tbese criteria, tbe valley beam is considered to be loaded by a triangular distributed load with a calculated force ofzero at the bigh end ofthe beam and a maximum force of 488 pounds-per-linear foot (pH) at the low end of tbe beam. Our analysis was also based on an assumed wood grade of Soutbern Pine #2 for the valley beam, and we also assumed that the two existing ridge beams near tbe valley beam are botb directly supported by king posts or bearing walls. A ridge beam wbich is not directly supported requires rigid-frame action in the rafters wbicb span between the ridge beam and valley beam. Thus, more load would be imparted to the valley beam being examined if tbe nearby ridge beams were not supported Using tbe design criteria described above, KJG Engineering's analysis bas determined that additional reinforcing is required at tbe 2x12 splice location. Additionally our analysis revealed tbe need for an additional support to be added near tbe bigh end of the beam to reduce the forces at the splice location. Reinforcement at tbe new support is required as well. These recommendations are fully detailed on the two sketcbes attached to this report. Please note the KJG Engineering bas never visited this property, nor were we requested to analyze any structural components in the house other than the valley beam addressed above. Our calculations and recommendations are based solely on the construction drawings prepared 527 Sagamore Parkway W, Suite 101, \,Vest Lafayette, iN 47906 OtTice (765) 497-4598 Fux (765) 497-459l) by RAK Home Design and the as-built dimensions provided by Henry Poor Lumber Company. If any of our assumptions stated above are known to be inaccurate, please contact KJG immediately as a revised analysis may be required If you have any questions regarding this report or if you require structural engineering services in the future, please contact KJG Engineering Sincerely, 4/~ Jeremy S Duff, P.E. 527 Sagamore Park\\-,l)' W, SUIte 101, West Lafayette, IN 47906 Otlice (765)497-4598 Fax (765)497-4599 Z ::..." ,-; * ~i, -1: " - ,"'" ~j UJ.
