Dear All Sefians,
As a frequent visitor to this very important forum, I have been noticing that there are less activities or discussions as compared to the previous days in this forum. Many of the users seem to have preferred to other forum such as telegram groups, youtubes and others. One of the reason may be less response to the queries from the users since it is a voluntary activity.
Though I may not be able to answer the queries, I have been considering this forum as a source of knowledge where eminent mentors like Dr. N. Subramnian Sir, Vikram Jeet Sir, T. Rangarajan Sir, Jayakumar Sir, etc provided answers or responses to many queries not only from India but from all around the world. Provisions given in the BIS codes, which are not always clear, have been clarified or discussed here. What I expect is to keep this forum interesting and active with more discussions and responses so that experts could act as mentors to all beginners like me in the field of structural engineering.
I wish to know your views in this regard.
with regards,
Aditya

Yes Er Aditya

When the Forum started , for each query , there were many views and discussions were very interesting due to wider participation in expression of thoughts.
Presently , the participation is very feeble and sometimes queries are left unanswered.  There could be many reasons :

Other  sources of expression as mentioned by you

Structural and civil engineers , those working , definitely have to attend to their day to day design projects . Str job being highly demanding , engineers are under work pressure always. May not get time  to express.

Retired ones can contribute , but  Old Doctor is always occupied

Lack of interest in  understanding structures behaviour due to software availability , ready available spreadsheets

Dear Er.Aditya,

You are right !
Proliferation of several Structural Engineering Whatsapp  & Telegram groups has led to drastic reduction in the queries raised and discussions in SEFI. People are attracted to those groups because, instant discussions with several stalwarts are possible in them. But, please bear in mind that "Old is Gold". You can unearth old treasures ( discussions & solutions to any problem) from SEFI, by simply using search engine.

Best wishes,
E S Jayakumar

Dear Engineers
This forum has been confined to designs only, but try to understand that design alone is not adequate in world of engineering
How to achieve quality for a successful design must be made an issue
No one has tried anything as such, in this regard
Public is interested in good quality
Quality that is available is rubbish everywhere
I sometimes feel so angry if responsible engineer is met must be condemned for no one cares about quality
Nation is being destroyed in civil construction just for no one is serious, pertinent achieving engineering quality
On this forum quality is foreign continent
Remember that designs are scraps, if not transformed to reality!

Yes , design is directly dependent on QUALITY and designer , though sitting in design office,  is equally concerned about Quality construction and very rightly said by P engg Suraj saheb that design alone is not enough in the world of structures.

But engineers at site must be exposed to seminars / workshop on quality regularly from their organisation's  . Designers also need such sessions to provide details , notes , cautions , box instructions , and site visits.

Concern for Quality is obvious to one and all associated with project.

Dear Er. Siraji and Dr. Vikramji,


We are witnessing collapse of different kinds of structures at regular intervals in India. I believe this is due to the problems during construction.  We now use sophisticated software packages for the analysis and design. The design is by the more refined and rational limit states method. The concrete strength used is also higher than in the 1980s. We use fly ash and GGBS in the mix which reduce the pores and heat of hydration.  

But, at site we might see people who may not have sufficient knowledge about mix design, development length, joint reinforcement, curing etc. which are important for the strength and durability of structures!

Regards
Subramanian

Hi Aditya,

You make an important point. I think that the past two years of the pandemic have taken its toll on all of us including the SEFI community. I see a sort of lethargy sweep over  engineers. In fact, it would be very interesting to talk about the current state of affairs of the engineering community in general and the structural engineering in particular.

The struggles of fellow structural consultants as they try to get back their team together into the office are apparent. A lot of the engineering and CAD technical teams are pushing back against Work from Office directives. Some consultants have told me that they have lost up to 30% of their staff. "The Great Resignation" has visited the Indian shores too. You may have read the piece that talks about attrition at Infosys, TCS and others is as much as 27%. https://www.fortuneindia.com/enterprise/infosys-accused-of-invoking-non-compete-clause-to-curtail-high-attrition-2/107873.

This is a "Ship of Theseus" situation. Organisations are putting in desperate  non-compete clauses to discourage such rampant ship-jumping by engineers.

On the other hand, work on code revisions is ongoing. Rest assured, when the new codes are published SEFI will have a special online  workshop on the same.

You may    let us know what specific topics you would like   discussions on. Dr Subramanian has suggested  the topic of Failures of Structures. V Important and yes, let's discuss on that topic. Let me see the kind of traction we get to this post, and then we will decide.

Best regards,
Alpa Sheth

One of the issues for these kind of problems is the unrealistic timelines being set by clients for completion of projects for various reasons.. This results in poor supervision and thereby substandard quality of construction...

Thanks to Prof Subramanian and others for bringing out these important issues. From my own experience, I feel that now-a-days poor execution, contaminated mixing water, insufficient curing of PPC concrete, low cover, and improper admixtures are the main issues in the premature deterioration of RC structures. Besides these, lesser amount of cement than the prescribed quantity, poor quality of fine aggregates and higher amount of mixing water have been observed.

Regards,

One of the most important stage in construction industry which is missing in indian construction is that preparation of shop drawings based on engineering drawings.
Unfortunately construction is being done directly on design drawing which is not the correct practice.
Shop drawings to be prepared by contractor and should get approval from PMC or by designers.
Shop drawings are the drawings where it reflects Contractors work strategies based on logistics, understanding of design assumptions , coordination with other disciplines and so on.

The stages of construction are most important and can affect design,  durability,  cost and time of structure.

The power of shop drawings is such that approved shop drawings can supersede design drawings

Unfortunately such an Important aspect is not followed in Indian construction industry. If this step is implemented , the confirmation of design assumption, quality,  time and cost aspects,  durability can be achieved.
