Pr 4 For The Rectangular Beam Section Shown Below You Are Required To Consider The Stress Strain 0 Curves Of Conc 1 (73.41 KiB) Viewed 26 times

Pr. 4) For the rectangular beam section shown below, you are required to consider the stress-strain (0-€) curves of concrete in compression and reinforcing steel as presented below. If it is known that the section undergoes tension failure (when the extreme concrete fiber crushes &c=0.003), the reinforcing steel has already yielded εs > Esy); (a) Draw the stress profile of concrete on the given figure. Assume concrete does not carry any tension. (b) Find the strain on steel (es) and the resisting moment (M). Note: Do not use rectangular stress block in this question, use the stress-strain curves of the materials as given below. Oc (MPa) &c=0.003 Concrete 18 LLE И. ES 0.0015 =0.003 (+) Steel As=1571 mm (MPa) 365 + bw=250 mm 8 =0.001825
