Transcribed Image Text: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
Step by step
