Session 20 : Approach towards retrofitting of the structures

LIVE TECHNICAL DISCUSSION SERIES

Brief about topic :

Retrofitting of structures is indeed a vast science. The whole process of retrofitting may not yield the intended purpose if the appropriate approach is not used. The entire process may be divided in two parts, firstly, preliminary evaluation and secondly, detailed evaluation. The preliminary evaluation may aim to access the root cause, requirement of retrofitting, retrofitting scheme, tentative budget, etc. Finally, in the detailed evaluation, the exact structural analysis, design, detailing for retrofitting, etc. may be emphasized.  In the upcoming live session, we will discuss this important area wherein Dr. Dilip Khatri will share his insight on the subject.

Design of PEB structures Challenges and Way forward (Part 1)

We have seen the difference of opinion between group of engineers while designing the PEB structures. I believe there are many areas related to PEB structures wherein discussion is required. We have received many requests from engineers to host a live discussion on this important subject. 

Few of the questions, received from the group of engineers are listed below:

1)    What are the differences between design of PEB and conventional steel structure?

2)    What are the codes to be followed for design of PEB structures?

3)    Is section-12 of IS 800:2007 is applicable to PEB structures?

4)    How to design the anchor bolts for PEB structures?

5)    How to decide support condition for PEB structures?

6)    What are the design parameters to be considered in the software for design of PEB structures?

7)    How to decide minimum web thickness for built up I sections?

8)    How to estimate wind force for design of the low-rise structures?

9)    What is lateral torsional buckling and why it is critical limit state for PEB structures?

10) Can we consider Z purlins as giving lateral support to main rafter?

 As it is a vast area, we are planning to create short term modules for design of PEB (steel) structures focusing on the practical difficulties.

With an aim to collate such practical difficulty areas in design of PEB structures, the live technical discussion is organized.

 Date : 14-MAR-21

Time : 11:00 AM IST

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 buildings, Tony 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 14- Live Technical Discussion Series : Design of RCC Structures (PART 1)

Background :  We created a telegram group for structural engineers with a purpose of knowledge sharing and to serve as a medium for discussion related to technical matters, professional issues, guidance for young engineers, career advice, etc.

Link for joining the group : https://t.me/StructuralEngineering1

Dr. H. J. Shah had replied to number of queries in the group. In the next live session, we would like to summarise and present them along with the sketches. We wish to take up following points in the next live session :

  • The building columns are classified based on various criteria as (a) Braced and unbraced, (b) No-sway and sway, (c) Tied, spiral and Composite, (d) Short and long, (e) Axially loaded and eccentrically loaded, and (f) Ordinary and Ductile.
  • The buildings are classified based on the type of columns and walls occurring in them. Both are dependent on each other.
  • In addition to primary stresses, Gravity loads result in buckling, while horizontal loads try to overturn the building. In both the cases, moments are induced. Sufficient factor of safety should be there against overturning.
  • Buckling of a local column due to gravity loads is taken into account by using additional moments in columns which may be negligible (short column) or considerable (long column). To decide whether the column is long or short, we need effective length of the column that can be determined as per guidance of IS: 456.
  • Horizontal loads result in building sway. This sway may be negligible or considerable. The total horizontal shear acting on storey, Vi, will induce a moment equal to Vi hi where hi is the height of the ith storey.  This is called primary moment.
  • Relative sway of consecutive storeys is called drift. Due to drift, the vertical loads become eccentric and induce moments equal to, where  is drift of the storey. This is called P effect. The total moment induced due to loads on all vertical elements of the storey = S P, is called secondary moment.
  • Ratio of secondary moment to primary moment represents an index of stability of the building called stability index, Q. If Q is not greater than 4%, the lateral sway may be neglected and the columns in the storey may be considered as no-sway. If Q > 0.04, the columns in the storey may be considered as sway. IS: 16700, refers Q as inter-storey drift stability coefficient, q. For stability of building, .
  • Once the loads on the columns are calculated, we can design the columns. Note that there are a number of load combinations through which the column should pass.
  • Interaction diagrams are prepared for column design. These may be global or local.
  • The interaction diagrams as prepared by SP: 16 are global and can be used for variety of dimensions and materials used in columns.
  • An interaction diagram as prepared for one column with given dimensions and materials is called a local interaction diagram. It will be used to design a particular column with a number of load combinations.
  • Columns for a given storey are designed at top and bottom with given load combinations. If I am considering 25 load combinations, one column should pass through 50 column design calculations. Then one can get area of reinforcement.
  • Deciding the sizes of columns, the grade of materials along the height of the building requires through knowledge. Similarly, arranging the reinforcement along height, number and diameter at a section, is also a skilful job.
  • After arranging all, you need to satisfy strong column – weak beam analogy as per IS: 13920.

We wish to take up the above-mentioned areas in the upcoming live session. For making the session more successful, you are all requested to send your queries in advance. This will facilitate us to arrange the queries in order and prepare sketches for clarification, if required.

You are also requested to send your queries for following topics.

  • Shear Wall- Design and detailing of isolated shear wall
  • Hidden beam,
  • Floating columns,
  • Live load reduction
