Numerical Simulation of Ultimate of Slings for Three-Tower and Four-Span Suspension Bridge under Tanker Fire

Abstract:

Three-dimensional finite element model of Yingwuzhou Yangtze river bridge was established by using the finite element software ANSYS. Since the characteristics of bridge fire differed much from that of buildings, Heating curve HC_inc was selected as heating curve caused by tanker fire. Heat loading was imposed on the middle of main span where the tanker fire had taken place of three-tower and four-span suspension bridge . The temperature field and stress, modulus of elasticity, strength of sling changing with time caused by tanker burning in midspan were systematically investigated to obtain the failure time of the sling. The calculation also compared the above results of HC_inc curve with that of ISO834 curve. This research can provide some references to fire risk prevention measures of bridge during its service life.
