Problem #1. The base of a rectangular reinforced concrete beam is 300mm and the effective depth is 550mm. Concrete compressive strength on the 28" day is 24MPA and steel yield strength is 415MP.. Determine : a. The depth of compression block (in mm, 2 decimal places), the strain in the tension steel (5 decimal places) and ultimate moment capacity (in KN.m, nearest tenth) of the beam if it is reinforced with 4-32mm diameter bars. b. The depth of compression block, the strain in the tension steel and ultimate moment capacity of the beam if it is reinforced with 4-20mm diameter bars.

Question
Problem #1. The base of a rectangular reinforced concrete beam is 300mm and the effective
depth is 550mm. Concrete compressive strength on the 28" day is 24MPA and steel yield
strength is 415MP..
Determine :
a. The depth of compression block (in mm, 2 decimal places), the strain in the
tension steel (5 decimal places) and ultimate moment capacity (in KN.m, nearest
tenth) of the beam if it is reinforced with 4-32mm diameter bars.
b. The depth of compression block, the strain in the tension steel and ultimate
moment capacity of the beam if it is reinforced with 4-20mm diameter bars.
