A wooden beam is fabricated from one 2 x 8 and two 2 x 10 dimension lumber boards to form the double-tee cross section shown. The beam flange is fastened to the stem with nails. Each nail can safely transmit a force of 213 Ib in direct shear. The allowable shear stress of the wood is 76 psi. Assume b1=8 in., b2= 2 in., d1= 2 in., d2= 10 in. (a) If the nails are uniformly spaced at an interval of s = 2.9 in. along the span, what is the maximum internal shear force V that can be supported by the double-tee cross section? (b) What nail spacing s would be necessary to develop the full strength of the double-tee shape in shear? (Full strength means that the maximum horizontal shear stress in the double-tee shape equals the allowable shear stress of the wood.) b1 Nails d2 Answers: (a) V = i Ib. (b) s = i in.
