“Feel the structure”

My blogs are all about structural analysis & designing of reinforced cement concrete(RCC) & steel structure. It will help readers to enhance their knowledge & skills. It will also help them to understand the importance of visiting the site to check work based on his/her designed drawings because structure failure may take place due to I'll practice at the site even though your design seems to be sound. Past history speaks a lot about it.

 I am a Structural Engineer. My main work frame is to analyze & design simple to complex structures. I encourage many young civil engineers who have just passed out from college and want to make a career in Structural Engineering. Also, my blogs will work as a tonic for some civil engineers who are already in this field but are feeling very low due to lack of knowledge and skills. My blogs are certainly going to bring not only their professional growth but also they will start loving this challenging field. It will indulge them to be more innovative

I believe in 4SDE.
S= Stability, S= Strength, S=Stiffness, S=Sustainability, D= Durability & E= Economy
4SDE is my basic principle for analyzing and designing any structure and the same shall be followed by any Structural Engineer. You need to be very sound for a few essential checks like strength(Shearing Strength, Bending Strength, Torsional Strength), deflection(Based on Stiffness), Durability(Based on the proper grade of material selection, lifetime exposure of structure to the environment) and Economy (Based on client’s budget).
         

Dear reader, if you want to make a profound career as a Structural Engineer, then it is very important for you to deeply understand concrete technology. Until & unless you are able to understand the chemical reaction taking place in concrete and adherence to its hydration product to different deleterious gases and liquid chemicals in the environment, you will not be able to judge which materials like  PPC or OPC or sulphate resisting cement is most likely to be used as far as durability is concerned. You will be astonished by knowing the fact,sulphate reacts with the C-H-S gel(complex hydration product of cement) and concrete gets expanded by 300% by volume. You can feel now, to what extent it can damage concrete by developing huge cracks and it further gives the path to ingress of other deleterious chemicals like chloride to reach reinforcement. Also, we should have knowledge of high-performance concrete-like high flow concrete & self-compacting concrete & its advantage of using in the heavily congested reinforced areas to avoid honeycomb.
       

And the last one is the economy. It requires rigorous analysis or you can say this is the most tedious part. In order to design buildings under the specified budget, we require a lot of reiteration processes giving optimum member size fulfilling 4SDE.


         My blogs will walk you through not only the theoretical concepts but also the practical aspects of design. Being cautious & focused at the site activity, certain things like design flaws & shortcomings from the design teams, errors done at the site by contractor & certain unbelievable assumptions followed at a site based on imagination and altering design drawings & misinterpreting drawings & taking unrealistic decision taken by their own(contractors, site engineers or supervisors) which creates havoc at the site can be minimized. I will share valuable data to warn you from time to time to be a sound as well as a cautious structural designer.
       Most importantly, even a practicing structural engineer will find something very new and innovative in my blog.
        Last but not the least, I will request all who read my blog to give their valuable observations/suggestions to improve its content.
