Help me how to design the REINFORCED CONCRETE BEAMS WITH IRREGULAR CROSS SECTION as shown in
figure 1 using the following parameters:
F’c = 3,500 Psi Fy=Grade 40 Stirrups = Φ10mm
Mu = 200 Kn-M All Concrete cover = 30mm Es=200,000 Mpa
Find the following:
- AC area of compression concrete stress block in mm. Assume z = 0.85dEff
- a height of compression concrete stress block in mm.
- c distance from the neutral axis to outermost compression fiber in mm.
- z actual moment arm for Mu=ØTz in mm.
- As actual area of tension steel in sq.mm.
- N quantity of Ø20mm steel rebars
- ЄS Actual Strain of steel
- ЄY Yield Strain of steel
- Check if the beam is singly reinforced concrete in the designed then conclude
Check: ЄY < = > ЄS - Draw the Working Drawings of the x-section.
