Calculate if the ultimate moment capacity of a 350 mm x 600 mm simply supported 9 m concretebeam reinforced by 5-32 mm steel bars is adequate to carry the maximum moment produced by theloading stated as follow: 20 KN/m to 40 KN/m from left support to 3 m span, 20 KN/m from 3 mspan to right support, and 90 KN concentrated load induced at 4 m from right extremity. The weightof the beam is included in the factored loads. fy=414 MPa, fc=34.5 MPa, d'=75 mm2. Design a simply rectangular beam to sustain an ultimate moment of 484 KN m. fc²=27.6 MPa,fy=414 MPa, main bar 28 mmo, stirrups 10 mm, d'=65 mm, and L= 8m.3. A rectangular beam has the following properties: fc=27.6 MPa, fy=414 MPa, d'=60 mm,As =2-28 mm, As=4-28 mm, d=350 mm, b=250 mm. Determine the design strength of the beam.
