Abstract

Steel construction joints are critical parts and determine the overall strength of the structure, one of which is when subjected to high temperatures. The performance of bolt connections on steel bridges is very important to be considered in bridge design. The research results on the performance of the steel beams need to be supplemented with the performance testing of the post-fire girder bridge bolt connection. Six steel beams with shear-type high strength bolt connection in the middle of the span were tested under monotonic vertical point load located at the beam mid-span. Three specimens use proof load in their connections (Proof Load Specimens), while the others use a snug tight bolt (Snug Tight Specimens). As control specimens, two specimens (SS020 Proof Load and SS020 Snug Tight) were tested structurally without combustion. Two specimens (SS700 Proof Load and SS700 Snug Tight) were tested structurally after being burned under 700oC. The other two specimens (SS900 Proof Load and SS900 Snug Tight) were tested structurally after being burned under 900oC. The experimental results combined with reviewed using a scanning electron microscope (SEM) to determine changes in the microstructure due to the temperature given to charged objects. The best post-burn connection in the field is bolted connection with proof load tightening because it can increase strength up to 11%. Even after being burned, the proof load joint still proves the highest performance than the joint without being subjected to initial tensile forces.
