Effect of the end and side connections to the hollowcore concrete flooring systems in fire

摘要

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