Steel–ultra-high-performance concrete (UHPC) composite beams offer numerous advantages, such as structural self-weight reduction, bending stiffness improvement, and tensile cracking limitation in slabs. However, few studies have focused on the shear performance of short stud connectors steel–UHPC structures. To this end, push-out tests were carried out to evaluate effect slab thickness, diamete...

The corrosion fatigue performance of high-strength bolt was studied. Based on the fracture mechanics theory and the Gerberich-Chen formula, the high-strength bolt corrosion fracture crack model and the fatigue life model were established. The high-strength bolt crack depth and the fatigue life under corrosion environment were quantitatively analyzed. The factors affecting high-strength bolt cor...

Abstract This research investigates the behaviour of novel U‐connector used in cold‐formed steel (CFS) truss‐to‐column connection. The novelty is reflected specially designed connector geometry and connection method within cross‐section thin‐walled C‐profile. installed inside can be exposed to tensile, compressive shearing action. shear thoroughly investigated using laboratory tests. Three diff...
