FAST-NEPAL: Regionally Calibrated Spectral Method for Reinforced Concrete With Masonry Infills

Reinforced concrete (RC) with masonry infill is one of the most common structural typologies in Nepal, especially Kathmandu Valley. Masonry infills are typically made solid clay bricks produced locally Nepal. This study aims to calibrate spectral-based analytical method, namely, FAST, for Nepalese RC-infilled buildings. The FAST method has been initially conceived Southern European RC buildings hollow brick infills. calibration achieved by reviewing code prescriptions and construction practices Nepal updating method. variables calibrated using different information sources a Bayesian procedure consider global local material properties bricks. FAST-NEPAL obtained then verified, considering single school design, which detailed state-of-the-art vulnerability assessment available. Being particularly suitable large-scale assessment, further validated data from Ward-35 Metropolitan City (in vicinity Tribhuvan International Airport) photographic documentation included geo-referenced database collected after 2015 earthquake prepared census purposes. comparisons show that can be conservative relative other more accurate at capturing low-level damage. makes approach preliminary prioritisation
