based on shear, bearing, and tension. The plates
are made of A36 steel and the four bolts on each
side of the splice are A325-SC with standard round holes
(7/16”) at 3 inch spacing. Assume the hole spacing is such that block
shear rupture is not a concern.

Beam W24 x 76 (A992, GR 50, Fy = 50 ksi, Fu = 65 ksi) T = 21 in.

11D) For the singly reinforced concrete beam sections described below, determine i) depth of the compressive stress block ii) acceptability of reinforcement ratio to minimum and maximums iii) design moment capacity. (reinforced concrete beam analysis)

  1. fy = 60 ksi f’ c = 6000 psi As = 7.07 in^2 b = 16 in d = 30 in
  2. fy = 60 ksi f’ c = 5000 psi As = 3.01 in^2 b = 12 in d = 20 in

Partial answers to check with: 1.i) a = 5.20 in, ii) 0.0039 >  = 0.0147 < 0.0239,

iii)  Mn = 872 k-ft; 2.i) a = 3.54 in, ii) 0.0035 >  = 0.0125 < 0.0213, iii)  Mn = 247 k-ft

11E) A rectangular concrete beam is to be designed using f’ c = 3000 psi, fy = 40 ksi, density of 150 lb/ft^3 , b = 16 in., d = 32 in., and h = 36 in. for a simply supported span of 35 feet. Determine the area of steel required to carry superimposed loads ( not including self weight) of 150 lb/ft dead and 400 lb/ft live. Assume the maximum coarse aggregate size is 1 in.. Check if the steel fits and if the steel reinforcement ratio is within limit. (reinforced concrete beam design)

Partial answers to check with: Mu = 235.8 k-ft, Rn < 200 psi (  min),  = 0.0052 and

 Mn=243 k-ft

11F) Design a rectangular beam for a 22-ft simple span if a dead load of 2 k/ft (including an estimated self weight) and a live load of 2.9 k/ft are to be supported. Use f’ c = 4000 psi and fy = 60 ksi, The height of the beam should be between 1.5 to 2 times the width (which should be in even inches). Assume there are #3 U stirrups and a minimum of 1” clearance between bars and between rows (3/4” aggregate). Do not use bars larger than #11’s. (reinforced concrete beam design) Partial answers to check with: Mu = 425.9 k-ft. Your Rn with chosen b & h can range from

290 up to 470 psi where  max =0.0205. To check if the bars fit, subtract 3.75 in for cover and

stirrups, the total number of bar diameters and spaces (no. of bars – 1) of 1 inch each. (Bars larger than #8’s have custom diameters.) If the number is negative, the section is invalid. If your final reinforcement ratio is bigger than the max, the section is invalid.
