21- ASCE-7-P-delta Effects Part-1-Main Concept- Dr. Noureldin

In highrise building design, important secondary moments and additional story drifts can be developed in the lateral-force-resisting system by P-delta effects. P-delta effects are the result of the axial load P in a column being moved laterally by horizontal displacements, thereby causing additional secondary column and girder moments.
In this video, I will explain about:
P-delta concept
The geometric stiffness
The stability coefficient
The intent of Section 12.8.7 in ASCE-7 is to determine whether P-delta effects are significant, and if so, to modify the strength and stiffness of the structure to account for such effects.
Key words:
seismic design of structures
earthquake engineering
earthquakes
dynamic analysis
Non-linear static analysis
Pushover analysis
Response Spectrum
Non linear dynamic analysis

Great explanation, thanks

[@user-fm7ru3kr5j]

Thank you very much

[@noorhanalkhatib4341]

thanks Dr. Mohamed. I have a question please, V1y is less than V10, so why in the first Approach we have to multiply the forces by 1/(1-theta), and that is mean we increase the forces to tack care of the effect of p-delta?

Is it applicable for wind load?

Can you share the pdf notes if possible..
