Structural Engineering & Construction Situation 69 (PH)

PAST BOARD EXAM PROBLEMS Structural Engineering & Construction Situation 69 Due to architectural requirements, a column is of T-section as shown: 6-25mm diameter bars 4-25mm diameter bars 10mm diameter tie Clear concrete cover = 40mm f’c=28 MPa, fy=415 MPa Assume that for all bars, fs=fy

1. What is the distance (mm) of the plastic centroid of the section from y-axis? (286)
2. Which of the following gives the location (mm) of the geometric centroid from y-axis? (277.4)
3. A load Pu=4155 kN acts along the x-axis, 420mm from y-axis. What is the resulting bending moment. (556.8)
