Analysis of SRB:
Step 4:
Formula for nominal flexure strength Mn?
Give this one a try later!
Mn = As fy [d - (a/2)]
, Note:
If SDNY, use fs.
Analysis of T-Beams
Step 5:
Stress Check; If still SDNY after changing assumptions, use Yarignon's Theorem.
A_T * ȳ = summation(An Yn)
Formula for Aconc and Z?
Give this one a try later!
Aconc * ȳ = Af(tf / 2) + Ab(a_c / 2)
Z=d-ȳ
Design of SRB:
Step 1:
Solve for ρmin and ρmax.
2015 formulae?
Give this one a try later!
ρmin = 1.4 / fy = [(0.25)(√f'c)] / fy
ρact = As / bd
, ρmax = 0.85(β1)(f'c / fy)(3/7)
Analysis of T-Beams
Step 1:
Finding bf.
For interior:
Give this one a try later!
Use the least of the following:
bf = bw + 16t
bf = bw + (s1/2) + (s2/2)
bf = bw + (ln/4)

Step 6:
Solve for the maximum moment Mu.
