1. Design a simply rectangular beam to sustain an ultimate moment of 448 KN m. fc'=20.7 MPa, fy=414 MPa, main bar 25 mm, stirrups 10 mm, d²=65 mm, and L= 7m. 2. A rectangular beam has the following properties: fc'=30 MPa, fy=345 MPa, d'=60 mm, As'=2-28 mmò̟, As=4-28 mm, d=350 mm, b=300 mm. Determine the design strength of the beam. 3. Calculate if the ultimate moment capacity of a 300 mm x 550 mm simply supported 10 m concrete beam reinforced by 4-32 mm steel bars is adequate to carry the maximum moment produced by the loading stated as follow: 20 KN/m to 41 KN/m from left support to 3 m span, 20 KN/m from 3 m span to right support, and 100 KN concentrated load induced at 4 m from right extremity. The weight of the beam is included in the factored loads. fy=414 MPa, fc²=34.5 MPa, d'=75 mm

fy=414 MPa, main bar 25 mm, stirrups 10 mm, d²=65 mm, and L= 7m.
2. A rectangular beam has the following properties: fc'=30 MPa, fy=345 MPa, d'=60 mm, As'=2-28
mmò̟, As=4-28 mm, d=350 mm, b=300 mm. Determine the design strength of the beam.
3. Calculate if the ultimate moment capacity of a 300 mm x 550 mm simply supported 10 m concrete
beam reinforced by 4-32 mm steel bars is adequate to carry the maximum moment produced by the
loading stated as follow: 20 KN/m to 41 KN/m from left support to 3 m span, 20 KN/m from 3 m
span to right support, and 100 KN concentrated load induced at 4 m from right extremity. The weight
of the beam is included in the factored loads. fy=414 MPa, fc²=34.5 MPa, d'=75 mm
