An introduction to Engineering Calculation
In this chapter I will present you the formulas and parameters which we will use in our engineering calculation. We are calculating here deflections of reinforced concrete slab which is a typical structural engineering task. This is just an example of calculation, but you can use the same principles presented here to perform any custom calculation you wish to.
First we have a few calculation formulas for the properties of cracked and un-cracked concrete cross section.
We need to perform a calculation in all six points of the moment diagram. So that we can finally calculate time dependent deflection as an integral, which is approximated with this simple formula as seen here.
