What is the difference between the calculation of the axial force of concrete and steel support?
Axial force calculation is the same. But there are differences in the specific design calculations.
There is no big difference between the calculation of the axial force of the concrete and steel support. There is a slight difference in the weight of the rod.
In addition to calculating the compressive strength of steel support to meet the requirements, but also to calculate the stability of the requirements to meet. Because the steel support is generally longer and thinner, it may be unstable.
