IS 875 (Part 3):2015 | Session 90

INTRODUCTION

SQVE STRUCTURAL SUMMIT | SESSION 90

IS 875 (Part 3) : 2015, the Indian standard for wind loads on buildings and structures, is one of the very important document structural design practice. Whether you’re working on a low-rise industrial shed or a tall residential tower, this code plays a crucial role in estimating lateral loads and ensuring structural safety. With the document currently under revision, this is the ideal moment for the engineering community to come together and reflect on its application, effectiveness, and the challenges faced in real projects.

We are hosting an open brainstorming session that invites structural engineers, designers, consultants, and code users to share their doubts, practical difficulties, and grey areas they encounter while working with IS 875 (Part 3):2015. This is not a lecture — it’s a collective exchange of ideas. We encourage engineers to bring in queries related to wind speed zoning, interpretation of terrain categories, topography factors, pressure coefficients for different roof shapes, issues around the dynamic response of tall structures, cladding and façade design pressures, risk coefficient considerations, gust factor calculations, etc.

This session is meant to be a space to ask questions, share field experiences, and contribute ideas that may even influence how the revised code evolves. Whether you’re an experienced professional or a young engineer just stepping into structural design, your questions and insights are welcome.

You may share specific queries, doubts or discussion points related to IS 875 Part-32015 in advance through registration form.

JUST TO APPRECIATE THE WORKSHOP STAAD-STR-001, IT HAS BEEN VERY USEFUL FOR ME. I WOULD LIKE TO HIGHLIGHT THE DYNAMIC OF THE SESSIONS, VERY ACTIVE, INTERESTING, AND WELL ORGANISED AND GREAT TO SHARE EXPERIENCES. MANY THANKS TO THE SPEAKER AND ORGANISERS!!…..ONCE AGAIN THANK YOU FOR SHARING AN INSPIRING LEARNING EXPERIENCE 👍

Dipal Trivedi

The course GEO-STR-001 effectively addressed the gap between geotechnical and structural engineer. It not only covers important interface areas but also discusses consequences of poor interface. Subject experts have in depth knowledge and experience to address expectations of various participants ranging from fresh engineering graduate to highly experienced professionals. The course is interactive and experts are more than willing to address any queries of the participant. The course content is appropriately divided into multiple sessions over the weekend to allow flexibility to participants to participate and reflect during the week at their convenience. Overall, this course is highly recommended for structural and geotechnical engineers for gaining and enhancing the understanding of the very important interface between geotechnical and structural engineering work.

Chokshi Hem

I heard somewhere that we shall never use STAAD for dynamic analysis. But that wrong interpretation of the software was cleared through the course : STAAD-STR-001.

Er. Sachi Parekh

I appreciate the course structure designed by Er. Bhavin Shah , which includes the theory and implementation of coddle provisions to software and interpretation of results. By attending it, I am able to learn and explore the analogy of a software – Staad Pro. Thank you very much for sharing the knowledge and make my doubts crystal clear…

I must say that he is a true professional academician
Like a bridge between Institute and industry…

 

Dhirender Singh Bisht

I am pursuing masters in structural engineering and steel was the topic that I found always challenging since my B.Tech times. Moreover this is also a missing topic for the syllabus of many universities in masters program. To understand its theory ,and execute it practically in software is really challenging and need a mentor for that. I’ve been following Bhavin sir from last few months and was it was my good decision to choose him as a guide. By the course STEEL-STR-001, now I can feel that I am in a position to explore boundaries of IS code, and also I’m enthusiastic to see how Euro code, AISC code and other countries code tackles the problem which sounds to be complicated in IS code.

Sujata Gupta

It gives a good awareness about software as well as corresponding codal provisions. So one can get technical knowledge as well as how software using clauses giving in codes. Teacher is very patient, soft spoken and knowledgeable person. Topics selected in the course STEEL-STR-001 are very relevant, useful and to the point for design and analysis of steel structure.

Akshay Thakur

REC-STR-001: The recorded sessions are more than anything for tackling practical difficulties…. and you bring some other professionals like dr. Jain and dr. Gupta is just like awesome experience for the student like me who are from tier-3 college who won’t get such a precious information… thanks to you also for the knowledge you impart… best luck to you and your team for this your initiative to resolve practical difficulties among aspiring structural engineers… 🙏🏻 once again thank you so much… because nobody in today’s era from structural engineering domain is wants to share the information, but you do… kudos!

Shefali Thakkar

STEEL-STR-001 was the best interactive course ,wherein all practical facts and limitations those are related with prevailing standards, software and practices were discussed. Vision was provided to participate towards solving such prevailing limitations rather following the same collaboratively. Course content was described very effectively and constant encouragement on experiments of the course deliverables and raising doubts and solving the same. Effective time management by faculty to satisfy all participants’ queries along with effective delivery of course content. 24 hour interaction facility was made available for solving course related queries.

Akash Solanki

STEEL-STR-001 was the best package for understanding the limit state design of steel structures using IS800:2007 along with its application in STAAD.Pro. Tremendous wealth of knowledge from Bhavin sir combined with queries by other participants really facilitated a great learning experience. Thank you for such an amazing course. I hope more such courses are on the way.

D. Nivetha

The Staad Pro Training sessions were extremely fruitful, informative and it gave deeper insights into the field of structural engineering. Bhavin sir had not only taught us the software of Staad Pro, but he had explained us several technical concepts based on his field experiences. It was an interactive session where sir had asked us questions and it helped us think a lot and come up with solutions. Overall, it’s been a great experience and this 25 day of training has taught me a lot and has inspired me to develop greater passion towards civil engineering.

Ashish Sawant

The course WIND-STR-001 is very informative. It clears basics of overall concept of wind flow. Thanks to Bhavin sir and Gupta sir for your guidance on wind loading.

Alok Rathore

After attending the course WIND-STR-001, I change my prospective towards structure and learn many concept.

It has been an excellent course and given me an in-depth understanding on ETABS and STAAD.Pro software . I feel more confident in my understanding and it helped me complete my major project in my B. Tech course .Thank you for all the support and excellent teaching. During the training program all my queries were answered quickly.

Mainak Ghosal

The Course WIND-STR-002 was very effective. It changed my perspective on not only wind engineering but also seismic loading analysis. Dr.Gupta also referred some excellent books which would not have been possible otherwise. Last but not the least, Dr. Gupta was kind enough to give me the charges of highlighting the errata for the Explanatory Handbook on Wind Engineering.

Kamlesh Mehta

In the course WIND-STR-002, I was not able to attend few lectures due to internet connectivity problem. But I have gone through the video lectures provided by Mr. Bhavin shah and it is positive point that any time any where we can watch and update our knowledge.

Rajashree

The course WIND-STR-001 facilitated discussion and understanding of concepts  in more detailed simplified manner under the experienced and knowledgeable professionals. Thank you Dr Abhay sir and Bhavin sir.

Dr. Vinubhai Patel

Praveen Upadhyay

Bhavin Shah is a fantastic trainer, very friendly and encouraging, it was a well-delivered and presented course (STAAD-STR-001) that was well received by the group. There was a great balance between theory and practice and the concepts were clearly and professionally explained.

Ravichandra

STEEL-STR-001 is very wonderful course. I have learned many things through this course. During session Bhavin sir interaction with the participants is very great with clear explanations. We are expecting these type of courses in future also.

REVA VENU V M

I am a budding geotechnical engineering professional. For three years I have worked as faculty in NIT and recently joined as project fellow- geotechnical engineering in a research Institute. Now I am in the transition phase of my career ie, shifting from academics to industry. My desire to become a geotechnical engineering consultant inspired me to join this course. As I don’t have much industrial exposure, attending the course GEO-STR-001 helped me to gain a lot of practical knowledge related to geotechnical engineering. Especially the discussions related to soil investigation, interpretation of soil report and interactive sessions were really amazing. Queries of other participants and the discussions associated with it,were really informative, as it mainly focussed on current industrial practices. Thank you Vivek sir and Bhavin sir for giving this wonderful opportunity. Hoping for a better support in my future endeavours too. Also expecting further courses related to this, in the coming future.

Parth Gandha

The course STAAD-STR-001 was really amazing an knowledgeable. As I fresher I gained so much knowledge about all the little things I didn’t know that were so much important. Troubleshooting of the software was the most important topic as a single wrong interpretation of the warning can totally change the outcome. I heartily thanks Shri Bhavin bhai and SQVE consultants for introducing such wonderful courses so that we can perform good in practice.

Haridharan M K

The online course EQ-STR-001 was very informative and it covered all the aspects of IS1893, IS16700, IS13920 and more important sharing the videos of the course which enabled to go through at any time.

BHARATENDU PATEL

This course related to STAAD.Pro and case studies was beyond the conventional software training. It helped me conceptualise the idea behind the behaviour of any structure, understand the special requirements between steel and concrete structures. Real life case study and interactive sessions made the learning more impactful.

Dr. Raksha Parolkar

Topics covered in WIND-STR-002 were new for me to understand, as it has never been covered in syllabus. But the way Dr. Abhay Gupta sir taught, explained the problems and shared his experiences, the subject got easy to understand. I feel proud of being his student.

Ajay Narayan Jadhav

The course WIND-STR-001 provided Excellent clarifications on IS875 clauses.

Nitin Sharma

I would like to thanks and appreciate for this helpful course comprising of STAAD PRO Training and Design concepts for RCC and Steel. In this module I have learned in detail about essential concepts for designing industrial buildings and gained an understanding of different types of Analysis. I also acquired the knowledge of different types of Codes. Moreover, l was introduced with FEM, design of foundation, anchor bolts and connections. All the sessions were very interactive and engaging. The valuable knowledge that i have gained in these two months will certainly be propitious to start my career as a structural engineer.

Kunal Patil

At first I never expected the sessions which are going to be conducted would be so knowledgeable. Day by day listening to Abhay sir touching every aspect from the codal point of view, few from his own experience. The mixture of everything made this course WIND-STR-002 very valuable and useful. Before this course I was trying to learn from everywhere how does this wind dynamic forces are to be calculated but through SQVE consultants arranging this webinar and learning under experience fraternity was worthwhile.

Prashanth N

The course STEEL-STR-001 was well planned and the sessions were very interactive and informative.

Mohd Ameen Irfan

Bhavin Sir is very experienced and expert in his field, He made the topics in online course STAAD-STR-001 very clear from the scratch and also addressed every student’s queries and problems very nicely!!!

Session 15 : A Q&A Session with Tony Rofail from Windtech on Wind Tunnel Testing of Tall Buildings

In continuation with the well received live panel discussions on what IS 875 : Part 3 says about the estimation of wind loads on tall buildingsTony Rofail from Windtech has agreed to participate in another live discussion on Wind Tunnel Testing of Tall buildings. This will be an interactive session where attendees can have their most pressing questions asked and learn about current best practice in wind engineering.

The webinar will start with the regulatory framework: when is it mandatory in India to use a wind tunnel study to determine the design loads on a tall building? Also, when is it economically beneficial to do so.

There are a number of wind tunnel testing methods to determine the loads on tall building structures. Each method has its particular advantage and limitation. This presentation will shed some light on which method is most suited to which type of tall building structure.

This Webinar will also elaborate on some of the more advanced analysis techniques used for the study of the response of tall buildings that exhibit complex modal behaviour or have a complex form such as rigid connections at high elevation and their effect on the transfer of wind loads between the sub-structures.

The effect of different methods of accounting for the directionality of the local wind climate will also be discussed.

The presentation will include some basic tips on how the building form can be optimised to significantly reduce the dynamic response of a tall building.

This live webinar cover the following learning objectives:

1. When is it mandatory and when is it recommended to undertake a wind tunnel study for tall buildings?

2. The various testing techniques available and which type should be used for what type of tall building structure.

3. How small changes to the building form can bring about significant reduction to the overall loads on a tall building structure.

Session 8 : Wind force estimation for tall structures as per IS 875-Part 3

As a part of weekly live technical discussion series, we had very interactive session for estimation of wind force for low rise structures. In the session of 1-Nov-20, we will focus our discussion on Tall buildings.

Wind forces & associated response of Tall buildings is much important not only for design of building but also from the point of view of acceleration & human comfort, surrounding wind flow pattern changes, glazings & facade design, pedestrian level comfort etc. Dynamic response evaluation is critical & particularly across wind response for tall slender buildings. Interference among buildings when they exist in a cluster are still not fully well understood and documented. Hence, our session on 1st November will be dedicated to Tall buildings.
