Question
A beam from the exterior balcony of a house has a base of 300 mm and a height of 500 mm
reinforced with 6-Ø16mm bars for tension and Ø12mm. Determine the following (f'c = 20.7 MPa
and fy = 415 MPa) using all the NSCP provisions and if the bars is found out to be in two-layers
rebars may be unequally distributed on each layer:
a. Depth of Tension zone
b. Actual Tension Steel Stress
c. The net tensile strain
d. The ultimate moment capacity of the beam

Expert Solution
Step 1

Given:

b = 300 mm

h = 500 mm

fc = 20.7 MPa

fy = 415 MPa

Main bars = 6-16mm bars

stirrups = 12 mm bars

Assume cover = 50 mm
