Performance-Based Structural Design for Seismic Zones
Building resilience in earthquake-prone regions demands more than standard code compliance; it requires innovative approaches that balance safety with practical design.This blog explores how performance-based structural design is transforming the way we create structures in seismic zones, ensuring both safety and efficiency.
Understanding Seismic Challenges
Traditional vs. Performance-Based Approaches
Traditional structural design follows prescriptive codes with standardized requirements. Performance-based design, however, starts with specific performance objectives tailored to each project's unique needs.
