A composite beam is made of three timber boards connected through a series of nails located on each side of the beam as shown in Figure 1. The nails are spaced s mm apart. S mm 40 mm X1 mm X2 mm 20 mm 20 mm Figure 1 The beam is fixed at support A and subjected to a uniformly distributed load of 2.5 kN/m along BC and two point loads at points B and C as shown in Figure 2. 3 kN 2 KN 2.5 kN/m A B С 1.5 m 3 m Figure 2
Solve the followings: a) Calculate the neutral axis and second moment of area of the composite beam (30%) b) Find the maximum shear force in the beam and sketch the shear force diagram. (25% c) Find the maximum shear flow at the flange-web intersection of the beam. (30%) d) If the shear capacity of each nail is X3 kN, what is the maximum spacing, s of the nails along the beam.(15%)
