Dear Sirs,
I hope this email finds you well. My name is Apoorv Nigam / Structural Engineer working for Amazon.
I am writing to seek clarification on a specific aspect of IS 16700:2023 "Criteria for Structural Safety of Tall Buildings."

My query pertains to the application of provisions related to Non-Structural Elements (NSE):

1. Are the NSE provisions in IS 16700:2023 intended to be applied only to non-structural members in tall buildings with a height greater than 50 meters?
2. Or should these NSE provisions be applied to all buildings, regardless of height?

Given the significance of this code in ensuring structural safety, a clear understanding of its intended application is crucial for practitioners in the field.
I would greatly appreciate your expert insight on this matter. If there are any additional resources or documentation that could provide further clarity on this topic, I would be thankful for that information as well.
Thank you for your time and assistance in addressing this query.

Hi Apoorv Nigam,
Yes, If the building height exceeds 50m, As per IS16700:2023you must apply the relevant provisions to all critical non-structural elements,not just the structural system.
If you refer Clause 1 of IS16700:2023 clearly states thatthe code is applicable to entire buildings exceeding 50m height, coveringaspects related to both structural and non- structural safety.
Again if you refer Clause 12 of IS 16700:2023 – Non Structuralelements (NSE) specifically lays out provisions for design, support andanchorage of architectural elements and building services ( It must be properlyanchored , designed for seismic and wind actions, installed such that they donot compromise life safety or serviceability)
If your building is over 50m and comes under IS16700:2023 than it must coverthe items listed in IS16700:2023 (Architectural Component or Element , Mechanicaland Electrical component/element listed on Page 16,17 & 18 )
You cannot exclude NSE from compliance just because they arenot part of the primary load bearing system. If the building is covered byIS16700:2023 (i.e >50m height), all critical NSE items must comply with therespective clauses in the code.

Ahsan Raza Khan

Also CL.1.4 States that we can also apply this code even below 50m Height Buildings So its better to design everything safely.

Dear Apoorv Nigam,
My understanding of the subject is :  
IS 16700:2023 defines Non-Structural Elements (NSEs) in tall buildings as components that are not part of the building's main load-resisting structural system but are architectural, mechanical, electrical elements such as parapet walls, billboards, elevators, fire sprinklers, lighting fixtures, cladding, partitions etc., that do not carry primary structural loads but can influence the building’s behaviour under seismic or wind loads.

These provisions apply only to tall buildings as they experience greater sway, acceleration, and dynamic effects, making NSE design essential to avoid hazards such as falling cladding, partition failure etc., during earthquakes. For other buildings these provisions are not mandatory and need not be applied.

Hence, Clause 10 of IS Code starts with the following statement.
"The non-structural elements (NSEs) of tall buildings shall comply with all relevant existing national standards and guidelines as laid down by the various statutory and non-statutory bodies as well as the client/owner of the building. In addition, specifications laid down in 10.1, 10.2 and 10.3 shall be applicable."

Best wishes

S.K.SAGAR
