consideration centre mass and centre rigidity for tall building without exposure to earthquakes
consideration centre mass and centre rigidity for tall building without exposure to earthquakes
(OP)
hi
for building, high rise which is not expose to earthquakes/seismic condition and only wind load is taken into consideration..
do we still need to check whether the centre mass and centre rigidity coincide?
i am not be able to find a code regarding this..
because as far as i know.. no need to check if no seismic condition as long as the building pass the storey drift and sway check
please correct me if i am wrong..
many thanks..

also - there technically are no buildings where seismic is not an effect. Whether it controls various aspects of design is another matter.

RE: consideration centre mass and centre rigidity for tall building without exposure to earthquakes
you mean that
if the building is design based on standard building code...the building already can sustain seismic?
is it what you actually implying?
so even though the building is not purposely design to sustain seismic loading, the code has already include the safety factor for this.
did you have any idea on where can i refer to this more further.
RE: consideration centre mass and centre rigidity for tall building without exposure to earthquakes
There are specific seismic provisions in building codes that are specifically for seismic design:

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
RE: consideration centre mass and centre rigidity for tall building without exposure to earthquakes
No - I mean that in most current building codes seismic design is always a consideration. You have to design for BOTH wind and seismic
throughout the building.
In some cases, wind load effects will be higher than the seismic load effects. You still need to check the seismic to verify this and compare them.
