Determine the reinforcement and corresponding moment for the reinforced ratios given below. Draw the variation Mr vs As. Solve the problem by using equations of equlibrium and use "equivalent rectangular stress block" for compression. The section and material properties will be taken from Table 1.
a) ρ=ρmin
b) ρ=ρb
c) ρ=ρmax=0.85ρb
d) ρ=(ρmin+ρmax)/2
e) ρ=ρl=0.235·fcd/fyd
f) εc=εcu=0.003, εs=0.003
g) εc=εcu=0.003, εs=0.010 |  |
Student number is a parameter for the section and the material properties.
| Last digit of the student number | 0-1 | 2-3 | 4-5 | 6-7 | 8-9 | | Material | C25/S420 | C20/S420 | C20/S220 | C30/S420 | C20/S220 | | b [mm] | 300 | 250 | 250 | 300 | 300 | | d [mm] | 460 | 460 | 560 | 410 | 560 | | d' [mm] | 40 | 40 | 40 | 40 | 40 |
