To further investigate the fire performance of PC hollow slab exposed to fire
numerical analysis is conducted in this paper on the basis of the previous experimental studies.A nonlinear finite element model using ABAQUS is set up to analyze the thermal performance of PC hollow slab in fire conditions.The simulated temperature field is consistent with the test results.Based on this
the nonlinear sequential coupled thermal-stress analysis is conducted.Full agreement between the predicted and measured time-displacement curves is observed.Therefore
the proposed finite element model can be used to predict the fire performance of PC hollow slabs and the obtained results provide a guidance to well understand the fire resistance.
