Abstract

Abstract

The behaviours of the unbonded prestressed concrete simply-supported slab are investigated under fire based on?the premise that the ISO time- temperature curve would achieve.From the test result, the general regularities of deformation?and the change of prestressed force are presented.Two important factors, prestressing level and thickness of cover, are?examined.The test results provide a basis for further research in the future.
- unbonded prestressing force,
- prestressing level,
- thickness of cover,
- elevated temperature curve
