Abstract

This research aims to conduct a pilot study for the in-fire performance of headed studs, commonly used in composite structures over the world. The robustness of the shear studs in fire appears to be a key element to govern the composite behaviour after a sudden local instability developed in structures such as trusses and cellular beams. In order to experimentally evaluate the residual strength of studs in fire, the standard push-out test was modified for a half of the original set-up to be equipped with a furnace. The adjustments allow the steel section to have a 3-sided exposure against fire. Under the Standard ISO fire, the modified push-out tests under loading were conducted to identify the failure mechanism of the studs in relation to temperature developments.
