1. Given the applied load and properties of a simply supported I-beam, determine the initial prestressing condition at the bottom of the beam by using basic concept method. Span = 34 ft H fc = 6000 psi WLL 3600 lb/ft WD=384 lb/ft Properties: As = 369 in² Ig = 50979 in4 ct = 15.83 in cb = 20.17 in Sb st = 3527 in³ = 3220 in³ e = 13.12 in Aps = 1.53 in² ft = 930 psi fpi = 1189000 psi
