Collapse risk assessment of strengthened concrete bridge pier under flood loads

A  fluid structure interaction using particle finite element method for the full scale reinforced concrete bridge is built to simulate the deformations of bridge piers under flood loads. The critical pier will then be tested using 6-degree of freedom system, from which the finite element model of bridge model will be calibrated. Fragillity assessment of bridge pier before and after strengthening will be performed to study the effectiveness of strengthening for enhancing the resilience of bridges under flood loads.
