Yan, R. (author), Xin, H. (author), Veljkovic, M. (author), Da Silva, Luís Simões (author)In traditional end plate column splices, bolts are placed double symmetrically on the four sides of square hollow sections (SHS). In order to reduce the required gap between the façade and the column, the end plate could be flushed on one or two sides of SHS for the column along the façade or at the corner of a building, respectively. However...journal article 2023

van den Berg, Niels (author), Xin, H. (author), Veljkovic, M. (author)Orthotropic steel decks (OSD's) are susceptible to fatigue failure due to cyclic loading. Often fatigue cracks are found in the joint between the deck plate and the trough. Due to the welding process, residual stresses are present in and around the joint. In this paper, the effect of residual stresses on the fatigue crack propagation rate has...journal article 2021

Xin, H. (author), Veljkovic, M. (author)Predicting the ultimate capacity of components made of high strength steel (HSS) is a numerically challenging task. The fracture performance of HSS from different steel grades, producers, and manufacturing processes (rolling, cold forming, etc.) varies greatly. It is costly to conduct a series of experiments for each typical HSS structural...journal article 2021

Cheng, L. (author), Xin, H. (author), Groves, R.M. (author), Veljkovic, M. (author)Acoustic emission (AE) is often used for structural health monitoring (SHM) in the wide field of engineering structures and one of its most beneficial attributes is the ability to localize the damage/crack based on the AE events. The vast majority of ongoing work on AE monitoring focues on geometrically simple structures or a confined area,...journal article 2021

Yang, F. (author), Liu, Yuqing (author), Xin, H. (author), Veljkovic, M. (author)Many bolted connectors were proposed for use in steel-concrete composite structures over the past few decades. This is because using bolted connectors could make the assembly and disassembly of steel-concrete composite structures more convenient and reusing the dismantled structural components could also improve structural sustainability. Lots...journal article 2021

Cheng, L. (author), Xin, H. (author), Groves, R.M. (author), Veljkovic, M. (author)S460 steel is increasingly used in civil engineering, especially in a harsh environment such as offshore structures [1]. Material damage is inevitable for structures subjected to static and dynamic loads during their technical life time. Thus, monitoring material damage is important for providing information regarding critical damage of in...abstract 2020

Chen, Zhuo Yi (author), Li, Chuan Xi (author), He, Jun (author), Xin, H. (author)Diaphragm cutouts are set to release redundant constraints and hence reduce weld fatigue at the connection of U-ribs to diaphragms in orthotropic steel decks. However, most fatigue cracks which originate from the edge of cutouts are in fact detected in the diaphragms. Therefore, a retrofit technology on cracked cutouts at the diaphragm is...journal article 2020
