• Advanced composites offer a 40% higher strength-to-weight ratio than conventional steel, reducing structural weight and foundation costs.
• FRP composites exhibit superior corrosion resistance, extending service life by up to 50% in harsh environments.
• Life-cycle cost analysis shows a 20% reduction in maintenance expenses over 30 years despite higher initial material costs.
• The study provides design guidelines for integrating composites in new and retrofitted structures, enhancing seismic resilience.
