Understanding nonlinear static analysis for seismic performance evaluation
Today, I had the opportunity to dive into Pushover Analysis using ETABS, an essential tool in structural engineering for seismic performance evaluation.
What is Pushover Analysis?
Pushover analysis is a nonlinear static analysis method used to understand how a structure behaves under increasing lateral loads, such as those caused by earthquakes.
Why is it Important?
It helps assess the capacity and ductility of buildings, ensuring they can withstand seismic forces and provide safety during earthquake events.
Displacement Coefficient Method
🔎 Today, I approached the Displacement Coefficient Method, a powerful way to quantify the expected displacement of a structure during an earthquake.
