Practice Problem 4.4 (CE Board November 2016)
Given:
Beam Dimensions, bxh=350mm x 450 mm
Effective Cover to centroid of steel reinforcement =
75 mm
Steel Strength, fy=415 MPa
Stimups, fyv 275 MPa
Shear reduction factor = 0.75
Beam is subjected to shear and flexure only
Concrete Strength fc=27.5 MPa
a) The beam is reinforced with 3 legs of 10 mm diameter stimups space 90 mm on center. Which of the
following gives the shear strength of the beam?
b) To develop a shear strength of 375 kN, find the spacing of 10 mm diameter stimups consisting of 3 legs.
c) Which of the following gives the allowable maximum spacing of 2 legs of 10 mm diameter stimups?
