ABSTRACT
ABSTRACT: A serial of numerical simulation by the software ABAQUS has been carried out to investigate the thermal response of boned-in anchor at elevated temperatures. The 3D model of steel-to-concrete connection with fire resisting coating is employed in this research and the development of temperature is supposed to follow the ISO834 standard time-temperature curve. Several variables including thickness of fire resisting coating, edge distance and embedment depth have been considered. The result shows that ambient temperatures have great impact on the thermal field of the whole connection and the temperature of adhesive anchor would reach above 160°C after a fire rating of 90 minutes even in the case of fire protection method has been used on the connection surface. Based on the comparison of parametric analysis, some advices are given for the fire-resistance design of bonded-in anchor.
