Safe Support Spacing and S-1 - bd Table below shows formulas for shear, bending moment and deflection for three-span continuous uniform load beam. R₁ = R₁ = 0.4wl R₁ = R₂ = 1.1wl Vmax=0.6wl Vdes 0.6w-wd+ Ma W(² Mmax=- 10 AT WA Amax 145E'I If the bending and shear stress equation, and allowable deflection values are given as follow: • fb = M/S • fv = 3V/2bd • A= 1/16" a- Calculate safe support spacing for this beam (express the safe support spacing as a function of several variable). b- Express the equations for section modulus, moment of inertia and bd. Hint: This is an exercise in deriving where the equations come from. Three-span, continuous, uniform load = -w(d+²2)
