โžก๏ธ Watch till the end to understand how engineers design earthquake-resistant structures using the Response Spectrum method.

๐Ÿ“Œ What is this video about?

Earthquakes can cause massive destruction by generating dynamic forces in structures. But how do engineers predict the maximum impact of these forces without running complex simulations every time?

In this video, we explain the Response Spectrum Method โ€” a powerful seismic analysis tool that helps engineers assess the maximum structural response based on natural frequency and earthquake time history. We break it down using simple analogies, starting from a ball-on-stick model, introducing equilibrium equations, and leading up to how the design spectrum is generated.

๐Ÿง  Key concepts covered in this video:
00:00 - Introduction to earthquake
00:10 - The intent of analysis
00:22 - Response spectrum
00:53 - What is a Time history?
1:50 - Equilibrium equation
3:10- How to plot the response spectrum?
4:00 - Design Spectrum
