Critical review of IS 1893 (Part 1) : 2016 - Dr. Ashok Jain

Introduction

Centuries ago, a large number of astonishing structures such as Kutub Minar, Taj Mahal and so many incredible palaces and temples were built in stone masonry in various parts of the country. Some of these temples have very tall shikhars with amazing carvings. They have so many delicate columns and non-structural elements. They are standing even today without any damage due to past earthquakes. However, is it possible to build similar stone masonry structures today? NO. IS 1893 (Part 1) will not let you. It has banned such structures explicitly in seismic zone III, IV and V.

The question arises who is wrong? Our ancestors or the modern day IS 1893 (Part 1) code? (Extract from paper of Dr. Ashok K. Jain)

The original paper was presented by Dr. Ashok K. Jain in the meeting of IAStructE on 11th May, 2017. Since then, a number of practicing engineers have made requests to discuss the various issues in more detail. In 2020, BIS has issued amendment no. 2 which is quite exhaustive. Recently, he has modified the document based on request of the practicing engineers.

In the upcoming live technical discussion, Dr. Ashok K. Jain will share his critical review about IS 1893 (Part 1) : 2016.

Dr. Ashok K. Jain is currently a structural consultant having over 40 years of experience. Formerly, a Professor of Civil Engineering at the Indian Institute of Technology Roorkee, Roorkee. Dr. Jain received his Ph.D. in Civil Engineering from the University of Michigan, Ann Arbor, MI in 1978. He received gold and silver medals in B.E. (Civil Engineering) and M.E. (Structural Engineering) at the University of Roorkee, Roorkee. He is well known for imparting latest knowledge on each subject/topic through latest analytic tools such as MATLAB, MS Excel, SAP2000, and ETABS.

Dr. Jain has published over 50 refereed journal papers and over 60 conference papers on various topics. He has authored five text books:

Dynamics of Structures with MATLAB Applications, Published by Pearson (2016)
Reinforced Concrete – Limit State Design now in its 7th edition (2012) – This book has the distinction of being the first book on the subject published in 1983 in India and enjoys excellent reputation till date.
Advanced Structural Engineering with Finite Element Method, 3rd edition (2015)
Strength of Materials and Structural Analysis, 2nd edition (2008)
Fortran programming, second edition (1990) – now discontinued

He has delivered keynote addresses in many conferences and conducted short specialist courses on Reinforced Concrete, water retaining structures, ductile detailing of structures, dynamics of structures and earthquake resistant design.

Session 33 : Experience of various structures design – Er. U. H. VARYANI

Post author By SQVe
Post date January 9, 2022

We are honored to have presence of Er. U. H. Varyani in the next live technical discussion. He will talk about his experience related to design of various structures during his professional career of 45 years.

Starting from a humble background, he graduated in civil engineering in 1958 from the Indian Institute of Technology (llT), Kharagpur and worked in India and abroad with many reputed firms of architects and government departments. He spent over a year in Germany and ten years in Libya. He has written four books and forty papers. He has designed about 2000 buildings, big and small, with the help of his design staff. Along with design of structures, writing on structural engineering has been his passion. Many young engineers have worked with him during his professional career.

In the next live technical discussion, he will share his insight and experience related to various structures design.

DATE : 12–JAN-2022

TIME : 7:00 PM IST

Please share the message with the other engineers in your circle so that more number of engineers may be benefitted.

Session 32 : Design life of RCC Structures (PART-3)

Post author By SQVe
Post date January 3, 2022

We had very interesting conversation related to design life of RCC structures on 3-DEC-21. Following are few of the points which were discussed during the session:

Importance of foundation parameters
Service life estimation of structures
Design life of structures vs actual life
Discussion related to interesting points suggested by online participants
and many more…

The entire recorded session is attached below.

Session 27 – Design life of RCC structures (PART 1)

SCHEDULE FOR NEXT SESSION

The next session (PART-3) is planned as follows:

DATE : 7-JAN-22

TIME : 7:00 PM IST

DISCUSSION POINTS TO BE COVERED IN THE SESSION

Following points will be discussed in the session:

Essential preventive care after 25 years of RCC Structures
How to check expected life of existing structure
Can design life of any structure numerically evaluated say certain cover will provide more corrosion resistance so is there any method that takes into consideration of cover thickness, grade of concrete etc to come up with design life of any structure.
How to analyse and retrofit the seismically affected structure?
We will also take up few relevant and important discussion points coming through the LIVE chat

There is no age for Learning!

Post author By SQVe
Post date January 3, 2022

Today, I would like to share an inspiring story of Shree Praveen Vasishth (BSc Civil Engineering, Msc Structural Engineering from Delhi college of Engineering). He is 70+ years old. He served Central Electricity Authority (CEA) at various positions, starting from design assistant to Director T.C.D. for overall span of ~34 years. During his tenure, he was involved in the civil & structural design of thermal power plants across the country. Unfortunately, he got permanent disability before ~3 years.

The physical limitations, substantial reduction in hearing capacity, older age etc. have not at all affected his desire of learning further. He attended our FOUR online courses (STAAD-STR-001, EQ-STR-001, STEEL-STR-001, ETABS-STR-002) in the last year.

I must say that he is one of the most punctual participant and having the highest attendance in all the four courses!

He is truly an inspiration for all of us that there is no age for learning and no physical limitations can restrict you if there is a strong desire for learning!!

We are going to schedule the courses based on demand of engineers. You may fill up the Pre-Registration form wherein you can select the number of courses as per your interest as well as you can suggest the new courses at following link. Your valuable feedback will immensely help us to prioritize the courses.

Keep Learning!!

Civil Engineering Engineering Geotechnical Engineering settlement in structure Structural Engneering

Session 30 : Acceptable value of settlement in structures

No Comments on Session 30 : Acceptable value of settlement in structures

Live Technical Discussion Series

(Soil Structure Interaction…)

There is always debate and discussion related to acceptable settlement in the structure. The settlement may be short term settlement or long-term settlement. Also, there may be uniform settlement vs differential settlement. Following are few of the approaches prevailing in practice, :

1) Permissible value of the settlement may be defined based on the tender specifications. Based on the settlement value, allowable bearing pressure will be determined by geotechnical consultant.

2) Permissible value of the settlement may be defined based on IS codes related to geotechnical engineering. Based on the settlement value, allowable bearing pressure will be determined.

3) Acceptable settlement value may be defined by structural engineer considering the functional requirements, stability of the structures, additional stresses in the structures, limit to prevent failure of non-structural elements like piping, utilities, etc. Based on the settlement value, geotechnical engineer will derive the allowable bearing pressure.

Generally, differential settlement component is not mentioned in the geotechnical investigation report as the geotechnical consultant may not be aware about the differential loading on the different foundation as well as variation of pressure across each footing (due to presence of overturning moment). We believe that close interface is required between geotechnical and structural engineer to derive the probable component of the differential settlement.

One more important area would be to consider installing of instruments for monitoring the settlement value during life of the structure.

In view of the above, next live technical discussion is arranged on this important topic wherein we will attempt to answer your specific queries/doubts related to the acceptable values for settlement in the structures.
