PROBLEM 4 300 KN 190KN 70 KN e-0.46m A timber column having a cross section of 250 mm x 250 mm has a total height of 8 m, which are supported at both ends. It carries an axial load of 300 kN and an eccentric load of 70 kN acting at an eccentricity of 450 mm at a point 5 m. above the bottom of the beam. Allowable compressive stress parallel to the grain = 12.44 MPa. Allowable bending stress = 9.13 MPa Modulus of elasticity = 13800 MPa. a.) Compute the allowable compressive stress of the column section. (Spts) b.) Compute the actual bending stress of the column section. c.) Compute the total interaction value due to axial and bending. 35 Gm
