Croatian Science Foundation project IP-2026-9677<\/p>\n\n\n

Road Bridges Under Seismic Fragility Assessment Accounting for Structural Condition<\/h1>\n\n\n

ROBUST aims to develop a condition-dependent methodology for seismic fragility assessment of existing road bridges in Croatia. By integrating structural condition, historical design characteristics, field investigations and advanced numerical modelling, the project seeks to improve the reliability of seismic fragility assessment and support bridge management.<\/p>\n\n\n
