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.
