Inclined or Raked Column Design
The main secondary effect of having inclined columns is that they introduce a horizontal component of the axial load into the beams/floor slabs at each level, so you need to design for these forces.Also, you need to be careful about additional moments caused within each floor height of column due to eccentricity of vertical loading.Depending…

Stair Modeling Clarification in Etabs as it may consider a Stair Slab as wall area object.
As per one case study, Etabs considers Slabs maintaining slope more than 3.63/10 as Wall area object. Whatever it considers that is not our concern, concern is-we have to be careful while using stiffness modifier for slab & wall (as they are different for each, for stair we will use modifier same as Slab). Although…

Why are I-shaped Steel sections so popular?
Suppose you have to tighten a nut of your bicycle and I tell you to do it by hand, will you be able to do it? No of course not, but what if I give you a wrench with a long lever, then I think you will be able to do it quite easily. The…

What is the difference between Membrane and Shell?
This is a global differentiation in all the finite element software. Membrane elements are used to represent only inplane stiffness of members. It acts like the bedsheet on your bed. The bedsheet does not have any kind of bending stiffness and so it bends without any resistance. So use this kind of element when you…

Concrete Core Testing: Sampling and Test Procedure
Concrete core test is a very famous and well-established testing method for the compressive strength of the hardened concrete. Concrete core testing enables visual inspection of the interior regions of the concrete member which is also related to strength estimation. Concrete coring also enables to evaluate other properties of reinforced concrete framed structure by concrete core test. In…
