Jeon, Jaemin (author), Kim, Jaeyong (author), Lee, Jong Jun (author), Shin, D. (author), Kim, Yoon Young (author)This study presents a new modeling technique to estimate the stiffness matrix of a thin-walled beam-joint structure using deep learning. When thin-walled beams meet at joints, significant sectional deformations occur, such as warping and distortion. These deformations should be considered in the one-dimensional beam analysis, but it is...journal article 2022

Numerical analysis and discussion on the hot-spot stress concept applied to welded tubular KT jointsVieira Ávila, Bianca (author), Correia, J.A.F.O. (author), Carvalho, Hermes (author), Fantuzzi, Nicholas (author), De Jesus, Abílio (author), Berto, Filippo (author)Nominal stresses have been used for a long time for the assessment of fatigue resistance of welded joints, however, this approach has strong limitations since the definition of the nominal stress may be subjective for complex welded details and/or complex loading. On the other hand, the hot-spot stress approach has been proposed to overcome...journal article 2022

Kongshaug, Simen Sørgaard (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Markeset, Gro (author)Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to loss of structural integrity. Two natural questions arise when assessing existing concrete structures affected by ASR: (1)...journal article 2022

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
