Question
The doubly reinforced rectangular concrete section shown in Figure A-1 is reinforced with
4N24 bars in tension and 2N20 bars in compression. The section has a width b= 250 mm and
depth = D mm.
Given: Concrete compressive strength fe = 50 MPa, yield strength of reinforeing steel. fg =
500 MPa. Find other required data from AS3600-2018.
a) Calculate the beam depth, D where D= 500+20n
[Take n = 5th digit of your student number. For example: your student number =
18503679, n = 3; D = (500 + 20*3)=560 mm]
Note: Use the calculated D from (a) for the further calculation in (b-c).
b) Calculate ultimate moment capacity (Mu) of the section.
c) Check ductility of the section according to AS3600-2018.
