Question A1. The doubly reinforced rectangular concrete section shown in Figure A-1 is designed for the hogging moment of a continuous beam. The section has a total depth of D mm, width B= 300 mm and is reinforced with 4N28 bars at the top and 2N28 bars at the bottom. Given: f. = 40 MPa, fy = 500 MPa. Find other required data from AS3600-2018. a) Calculate the beam depth, D where D = 500+20n mm. Take n = 3rd digit of your student number. For example: your student number = 18505679, n = 5; D = (500+ 20*5)3600 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. 300 4N28 2N28 Figure A-1

Transcribed Image Text:Question A1.
The doubly reinforced rectangular concrete section shown in Figure A-1 is designed for the
hogging moment of a continuous beam. The section has a total depth of D mm, width B= 300
mm and is reinforced with 4N28 bars at the top and 2N28 bars at the bottom.
Given: f. = 40 MPa, fay = 500 MPa. Find other required data from AS3600-2018.
a) Calculate the beam depth, D where D = 500+20n mm.
Take n =
3rd digit of your student number. For example: your student number =
18505679, n = 5; D = (500+ 20*5)=600 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.
