Question

SITUATION A: The floor system shown has the following applied loads.

Super Imposed Dead Load = 2.00 kPa

Live Load = 1.90 kPa

Slab Thickness = 100.00 mm

Weight of Concrete = 24 kN/m3

Self-Weight of the beam = 1.92 kN/m

Material Specifications:

f’c = 21.00 MPa

fy = 345.00 MPa

Steel Cover = 50.00 mm
