TITLE: FLEXURAL ANALYSIS OF BEAMS (STRENGTH METHOD)
PROBLEM:
A cantilever beam shown supports a uniform service (unfactored) deadload of 15 kN/m plus its
own weight and a concentrated service (unfactored) liveload of 53.4 kN. The concrete is normal-weight
concrete with f'c = 27.6 MPa and fy = 414 MPa for steel. Use unit weight of concrete equal to 23.5 kN/m³.
Required:
a. Draw the shear and momemt diagram.
b. Draw the strain diagram, stress diagram and the internal forces diagram.
c. Determine if the section is ductile using ACI 318-99 and NSCP 2015.
d. Check the adequacy using ACI 318-99 and NSCP 2015: ĐM, 2 My
