1. The following reinforced section below has a concrete clear cover of 1.5” all around and #4 ties. Fy = 60 ksi, f'c = 6 ksi, with As = 5 #9's. Use normal weight concrete. b=15" h=24" ps due The beam is ply supporte 12” wide columns and has a point load of 50 to live load at midpoint. Do not forget that the beam has self-weight. 20 ft (columns out to out) To prevent creep, the designer will add 3 - # 7's bars in the compression side of the beam above, and will neglect its additional strength effects. = a) Determine the expected long term deformation at service life. Assume Icr= 0.31g Hint: find service moment Ma and Mer so you can get le to be used in the beam long term deformation formula. b) What would the expected long term deformation at service life be if the compression reinforcement was omitted?
