Question

The precast floor beam is made from concrete having a specific weight of 23.6KN/m3. If it’s to be used for a floor of an office building, calculte it’s dead and live loadings per foot length of beam.

Step 1

We have been given the following information

Unit weight of concrete = 23.6 kN/m^{3}.

We are required to calculate the value of dead loading per foot length of beam and live loading per foot length of beam.

Considering the following precast floor beam section for the given question:

:

Step 2

The dead load can be calculated as follows:

Step 3

Now for calculating the live load, w...
