response spectrum analysis

Response spectrum analysis is a method used in engineering to predict how structures, like buildings or bridges, will respond to dynamic loads such as earthquakes or strong winds. It simplifies complex seismic activity into a spectrum of possible forces, showing the maximum expected response (e.g., movement or stress) for different types of structures. Engineers use this to design safer buildings by ensuring they can withstand the worst-case scenarios indicated by the spectrum, ultimately helping to minimize damage and protect lives during natural disasters.
