RE. 6842 Jessica St. -Inspection of Beam - W.O.#14725-GPlvl
As requested, a sIte visit was performed on November 18, 2002. The purpose of the visit was to
inspect notches made at each end of the 51/8" x 15" GLB located in the garage, The supports
at each end of the beam have been notched on the tension (bottom) face The notch at the
north end of the beam is 5.125" wide, 5.5" long, and 3" deep T 18 notch at the south end of the
beam is 5 125" wide, 5.5" long. and 4 25" deep.
Using NDS equation 3.4-3 with d=15", V:::5125-(500~(15112))=4UiOO#, b=5.125N, and d n=10.75P,
the worse case shear stress in the beam due to the notches is 171 psi The allowable shear
stress per NOS Table SA is 190 psi. The beam has adequate shear strength to resist the design
roads prescnbed by the code.
Due to the possibility, of the flexural strength being reduced b} a horizontal crack In line with
notched depth. W'x8'1lag bolts are to be installed 2" from each elld. See detail included with this
letter. The deflection of the beam is not significantly affected t y the notch at the ends of the
beam.
Thank you for this OPPol1unity to be of service The enclosed Building Analysis Report and
Statement of Conditions and limitations Is a part of this report. f you have questions regardIng
this report, please contact me at 484-9080.
