Seismic analysis is the study of how structures respond to earthquakes and ground vibrations. It involves evaluating the effects of seismic forces on buildings, bridges, and other infrastructures to ensure they can withstand potential earthquakes. Engineers use various methods, including computer simulations and physical models, to predict how these structures will behave during seismic events. This analysis is crucial for designing safe and resilient structures, especially in earthquake-prone areas. By understanding the principles of seismology and applying them to engineering, professionals can create buildings that minimize damage and protect lives during seismic activities.
