Abstract

Purpose. The article is dedicated to the features of determination of fire resistance of prestressed concrete slab with unbonded reinforcement.

Methods. The fire test of concrete slabs with unbonded reinforcement of fire resistance. Computer modelling of concrete slabs with unbonded reinforcement of fire resistance.

Findings. The fire resistance limit of prestressed concrete slab with unbonded reinforcement and critical temperature for reinforcement are determined. Critical temperature for the reinforcement is defined according to the results of field tests and solving the inverse problem. The calculation of fire resistance of concrete slab with unbonded reinforcement is fulfilled in the ANSYS.

Application field of research. The obtained research data could be used in calculation and design of prestressed concrete slab with unbonded reinforcement.

Conclusions. In the article the model of reinforced concrete slabs with unbonded reinforcement is constracted. The behavior of the model under standard fire exposure is studied. The fire resistance limit of prestressed concrete slab with unbonded reinforcement and critical temperature for reinforcement are determined. The fire resistance of the model is estimated. The simulation results are compared with the experimental data.
