performance-based earthquake engineering

Performance-based earthquake engineering (PBE) is an approach that designs buildings and structures to behave predictably during earthquakes. Instead of just focusing on whether a structure can withstand a quake without damage, PBE considers specific performance goals, such as limiting damage or ensuring safety for occupants. Engineers use simulations to assess how different designs perform under various earthquake scenarios, allowing for smarter choices to minimize risks. This method balances safety, cost, and functionality, ensuring that structures can withstand seismic events while providing a clear understanding of potential outcomes during an earthquake.
