Determine the nominal concrete cover for a simply supported beam
with exposure condition XC4. The concrete strength is 25MPa, the
diameter of tension reinforcement is 32mm, diameter of shear link
is 10mm, design working life is 50 years and the quality control is
normal.

Consider a concrete beam in an interior environment as follows:
a. The beam is simply supported with a design span of 4.8 metres.
b. The dead load in the beam is uniformly distributed. c. Dead load
on the beam, in addition to its own weight, is 6.9 KN/m of which
75% is permanent (long term). d. The beam carries a single
concentrated live load at mid-span of 70 KN. e. 20% of the live
load is considered short term. f....

Determine the required shear reinforcing for a simply supported
concrete beam 7 meters long with a cross section of 500 millimeters
in depth and a width of 380 millimeters. Use fc = 35 MPa fy = 400
MPa. The longitudinal steel uses one row of 25M bars. The specific
live load is 29 kKn/m. The beam is not exposed.

2. A simply supported rectangular concrete beam is to be made
from M21 concrete grade and reinforced with steel bar of 345 MPa
yield strength. It carries a uniformly distributed load of 12.5
kN/m and has a span of 6 m. Design the beam, assuming that the
shape factor is 0.4. The weight density of steel is 77 kN/m3 and
that of concrete is 24 kN/m3.
