Drawings.

"Every other profession has its final product. A car manufacturer has the new model, a singer has her songs, a developer has the line of codes. For us Structural Engineer, we have our drawings, detailed by the analysis and design."

That's the pep talk our Head of Design Unit gave at the short welcome orientation. 

So today, I will be writing about the first task, other than the training ofcourse, I did after joining the company. It's called Beam Schedule. It's one of the final sheets we deliver the contractor/client.

BEAM SCHEDULE:

Beam Schedule is a table which informs a contractor of the required beam types in a building. It gives the quantity, size and the different beam types in a particular building. The number of reinforcing bars, stirrups/cadre required for each type of beam and the spacing between the bars. The table is an end product of a long iterative process, and it should be taken as such.

The size of a beam is given in terms of its Width x Depth. You can all imagine a rectangular block. The different types of beams are as per the end conditions: Fixed ends, Cantilever, A Continuous Beam, Simply Supported. The types of beams are determined by Us as per analysis results. 

There is no one correct way of updating a beam schedule. It varies vastly with Engineers, their preference and experience. But it does require a correct format. So, the following grouping is required to create a Beam Schedule:

1. Beam size.

2. Types of End Connections.

3. The reinforcement required. 

Extra remarks are always put in case of an irregularity.

Below is an image example of a Beam Schedule.











Here we can see a plan view of a floor with different annotations.

If we zoom to the center right, we have this view. I have marked two beams for easy reference, 89-CB1 and 89-CB2. This grouping is done as I explained above. After the grouping is done, we create the Beam Schedule.













As you can see, the schedule includes all the information required for the smooth working by the contractor. The reinforcement provided has been calculated considering all the reactions in the beam. The Bars Location indicates the type of end conditions.

As mentioned above, the schedule is highly subjective and can vary differently with Engineers. This is one way.

Ritz and Eigen.

Image
Ritz, not Rizz and Eigen Vector are two ways of solving a Modal Analysis problem. It is what ETABS use while doing the Modal Analysis. Today's blog will be about the difference between these two. EIGEN-VECTOR : It determines the undamped free-vibration mode shapes and frequencies of the system. What free-vibration means in our term is that there is no external loads acting on it for any period of time, just the initial conditions. The idea of bending a ruler and allowing it to reverberate. The natural modes obtained through this provide an excellent insight into the behaviour of the structure.  But remember, it's the free-vibration response while the structures will be under various different loads. What should be done then? Here comes the Ritz Vector. RITZ-VECTOR : Research has indicated that the natural free-vibration mode shapes are not the best basis for a mode-superposition analysis of structures subjected to dynamic loading : Wilson, Yuan and Dickens, 1982. I stole this l...

Modifiers.

Image
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...

Slab On Grade in ETABS.

Image
First let's know what an SOG is. The full form is Slab on Grade/Ground. One use for it to create an equal level for construction. Imagine a large area foundation with minimal area at a lower level. It is easier to provide reinforcement in a single plane; hence the lower level can be raised by filling it with soil or some other substances. Then it acts as one level foundation. I came across a scenario where I had to model an elliptical tank like structure, no columns in between. It was to be filled with soil. As you can see, I have attached an image, the slab span is quite large in between. The plan of the model. Imagine an ellipse with R1 = 37 m and R2 = 65 m. Now if you run the model as a normal slab, which it kinda is, one can easily guess the response. You can guess with experience that is, or a different case if you are a genius. I will tell you how the response would look like if you run it as a normal slab. You would get lots of local modes (I am assuming you know what local ...
