Simulation Analysis of Concrete Bridge Piers Subjected to Fire Disaster

A prestressed concrete bridge on the Wuxi Section of Shanghai-Nanjing Expressway was severely damaged due to a sudden fire disaster caused by crude benzene fuel.This paper analyzes the fired bridge piers in the fire core zone,determines the temperature field distribution inside the piers once in the fire disaster environment,evaluates the damage conditions of the piers and at the same time,gives the corresponding proposals for strengthening of the piers.
