What is Structural Engineer?

Draftsmen draft. Just kidding. They do draft but they are better than that, well! Some are. The need for a draftsmen might be meek in an ideal European sense, with all the automations and sort. Even without the automations, a Structural Engineer is expected to be able to do the drafting himself/herself.  But I don't live in Europe, do I? And the need also arises due to the sheer scale of some projects. The main task of Engineers is to design and analyse the structures. And it does take time. Hence, the need for draftsmen. Now what does a Draftsmen do. They draft. They are expected to be good in drafting softwares, whether it be 2D, 3D or even 4D. Though I have never been a part of a 4D project YET. Some general softwares can be the CAD lineup, Revit, Dynamo, Sketchup and the list goes on.  They should have the knowledge as how it all works. Some cases are not always general, and they have to come up with alternatives, just like Engineers in this case. For example, I had to imp...

This is one of the coolest concepts I have properly learnt at my job. I do know I will learn lot more on this. It's the Stiffness Modifiers.  It is a modification factor that is generally used in the properties of cross-section such as Moment of Inertia, Shear Area, Torsional Constant etc. It can also be used for Mass and Weight as per requirement. Modifiers for a typical Beam. Now why is it used? As the loads act on the structure, it will tend to generate cracks on the tension zone. Thus, reducing the area of cross section and stiffness of the member. 1 means the structure would take all of the loads, while 0 won't be taking any. It is kind of a paradox; the structure would resist all the loads if it is not cracked, and we know it will crack. In other way, we want the structure to not take the load as it will eventually crack. Concrete is weak in Tension. As per codes, IS Code ACI Code Now I have two great examples for putting my case. One is related to a torsion modifier I st...
