P-DELTA analysis is a geometric non-linear 2nd-order analysis.
P stands for the force acting on the body and delta means the horizontal displacement. It’s basically a destabilizing effect.
It’s commonly needed in tall and slender structures, where second-order effects can be significant.
It can identify potential stability issues, helping to ensure the structure is capable of supporting the loads it is subjected to without collapsing.
P-delta analysis has several advantages over traditional first-order (linear) analysis that are mentioned below:
◾ Improved accuracy
◾ Increased safety
◾ Greater flexibility
◾ Cost savings
◾ Design optimization
