AbstractTests of four post-tensioned high-strength self-compacting concrete flat slab specimens have been conducted under fire condition. Tendon distributions including distributed-distributed and banded-distributed patterns as well as various loading ratios were considered. Two of the specimens with lower moisture contents demonstrated excellent fire resistance performance, while the others with relatively high moisture contents experienced severe concrete spalling. The test results obtained from the tests are presented and discussed with respect to temperature distributions, deflections, crack patterns and concrete spalling. Moreover, numerical modelling employing the package ABAQUS has been conducted to help interpret the test results in order to get better understanding of slabs in fire.
