Welcome To Structural Madness

Structural Engineering is one of the most challenging engineering that one can experience. Undoubtedly building codes have made things much more easier but that is not the limit of this science, but in fact if goes even further.

If you think about structural engineering and your first class of structural mechanics, you always wondered about behavior of materials under different loading, how does bending moment affect a structure and why is shear always so critical. You get pretty confused and always looked for a good source to read about some "intuitive structural engineering". I have suffered through such problems and so I started writing down blogs.

Generally all the blogs about structural engineering talk about design methodology and how building codes define certain things and stuff like that. Well, that is all empirical. But that is now what we will do over here. On this platform we will understand the intuitive portion of structural engineering and discuss at the very basic level. If your basics are clear then everything starts making sense.

Would you like me to impress you with one basic example? So here it is, a basic concept of "Why development length is required in concrete structures?"

Let me give you the most simple example to explain the concept the development. Take your first finger and grab it in the palm of your other hand. Now pull the finger applying as much force as you can. At a certain limit your finger will slip and contact between finder and palm will break. But suppose if your finger is too long or the grip between the finger and the palm is immense such that if you pull your finger then the only way to get your other hand free is breaking up your finger. That is the base concept of development length.

The bond between steel and concrete is somewhat similar. We cannot have a continuous bar of steel throughout the structure. There are always connections, joints and splices. If we do not provide development length, then at the location of these critical areas the structure will fail easily. But if we provide sufficient amount of length to give a continuity to the strength of the structure then the strength will be similar everywhere. 

This is how we are going to discuss structural engineering over here. Taking very basic cases and understanding and applying them to a structure without breaking the laws of physics. Once we have covered all these basic concepts, we will discuss about building codes and clauses, nonlinear response history analysis, different software to use in structural engineering, artificial intelligence and neural networks and programming in structural engineering.

This is why the name of our blog is "Structural Madness". It clearly depicts the craziness towards the field. I do not consider this as my work, but instead as my hobby and passion.

So let's get started with our blog, shall we?


  1. Nice!!This blog is useful for us.

  2. Hi Jinal, I landed to your blog through your intuitive answers in Quora. I look forward to reading interesting stuffs. Have a great day !

  3. Hi jinal, i have completed my degree in 2016 and worked on site since them i wish to go on structural field but cannot figure out how should I. Hope you can help me

  4. My son is a 12 year old going into 7th grade and he is working on a science project that has to do with how high rise structures of different shapes react to wind loads. Would this be something you could advise him on and how a 7th grader could test? We have styrofoam structures roughly 3 feet tall by 1 ft wide in the shapes of a plus, a square, a star and a triangle.

    1. Yes, of course. Just send us an email on structuralmadness(at)gmail(dot)com and we will be happy to help him out. Thanks

  5. It is interesting bro..
    can you please make a video about vibration analysis basics.
    Vibrations and test in automobles also

  6. Sir can you tell me which books should I refer to learn structural engineering from basic level and also to become perfect in it?

  7. I am also aiming to do Masters in Structural Engineering and also have a blog on civil engineering and gives day to day info of this stream...

  8. Hi Jinal,

    I was very informative details about structural designing and structural engineering.
    I really liked the way you explain about the steel and concrete.

    Do write such awesome posts about structural designing.
    I did come across as website that might be useful for your audience.

    How to Calculate construction cost by using cost calculator tool:

    Hope these two links will help your readers to know more related to architecture and especially the calculator which helps to calculate the cost.

    Thnak you.

  9. Hi Jinal,

    I always find your topic intriguingly interesting. Can you advice me if there's a way to compute the vibration effect of pile driving to a house nearby? Hope to hear your exciting answer to this. Thanks. Be safe.

  10. This is an awesome post.Really very informative and creative contents. These concept is a good way to enhance the knowledge.I like it and help me to development very well.Thank you for this brief explanation and very nice information.Well, got a good knowledge.

  11. Hello I'm structural engineering student and curious about dynamic behavior of structure, I have one question,
    If we try to draw out relationships between height of buildings and magnitude of earthquake,
    Higher the magnitude will leads to lower frequency and higher time periods, so Is it correct that high rise buildings are more vulnerable in high magnitude earthquakes because of resonance? Or we need to look forward to any other consideration before coming to that conclusion.

    1. Hello Jasmin, I think you have either read some incorrect information on relationship between building height and magnitude of earthquake. The frequency content of the ground motion depends on the distance of site from the fault, type of soil and fault directivity effects. It has hardly anything to do with the magnitude of earthquake.

      Magnitude just describes the energy dissipated by the fault, in terms of fault length and ground motion duration.

      Higher magnitude typically either is a direct result of long duration of earthquake or high PGAs and not the frequency content. A tall building is susceptible to both high as well as low frequency vibrations. Low frequency vibrations will lead to large displacement demands in the building while high frequency vibrations will lead to distortions as well as higher mode effects and increased floor accelerations in the tall buildings.

      I hope this helps!

    2. thank you sir, this really helped.
