A 175mm x 400mm x 4m timber beam (simple span) is to be loaded with uniform load and a concentrated load of 30 kN at 1m from left support for a cumulative period of about 15 years. Consider wet service condition. Lateral supports are provided at ends only. An Agoho visully graded sawn lumber has tabulated allowable bending stress Fb = 26.3 MPa and modulus of elasticity E = 8220 MPa. Calculate the safe uniform load in kN/m for the beam considering all applicable adjustment factors. Blank 1
