Question

 A 3m-LONG CANTILEVER BEAM IS CARRYING A UNIFORM DEADLOAD OF 20 kN/m (EXCLUDING SELFWEIGHT OF THE BEAM), AND A LIVE LOAD OF 15 kN/m.

 

OTHER GIVEN:

fc = 27.5 MPa 

fy = 414 MPa 

b = 300mm 

h = 600mm

diameter of main reinforcements, db = 25mm 

diameter of transverse reinforcements, ds = 12mm

 

use clear concrete cover of 45mm unit

weight of concrete is 25kN/m3

 

Solve for the following:

a. Reactions at the fixed support.

b. Maximum FACTORED moment of the beam, Mu

c. Effective depth of the beam

d. As required

e. No. of 25mm reinforcements required to resist Mu

f. Spacing of stirrups at the critical location (d from face of the support) - use manual calculations, show your solutions.
