This paper analytically investigates the structural performance of hollowcore concrete floor systems in fire comparing several connection details which are verified to provide better seismic performance. The results show that the connections which are beneficial to the system’s seismic performance are not always suitable for the fire performance, and rotationally rigid connections provide better fire resistance than rotationally flexible connections.
