A review of concrete properties under the combined effect of fatigue and corrosion from a material perspective
Liu, Dongyun; Wang, Chao; Gonzalez-Libreros, Jaime; Guo, Tong; Cao, Jie; Tu, Yongming; Elfgren, Lennart; Sas, Gabriel (Peer reviewed; Journal article, 2023)When in use, reinforced concrete bridge structures not only experience high-frequency fatigue loading caused by passing vehicles, but also suffer from the effects of a corrosive environment. In addition to fatigue damage ... -
Experimental study on shear deformation of reinforced concrete beams using digital image correlation
Huang, Zheng; Tu, Yongming; Meng, Shaoping; Sabau, Cristian; Popescu, Cosmin; Sas, Gabriel (Journal article; Peer reviewed, 2019)This paper presents an experimental program aimed at providing reliable and comprehensive experimental data for assessing the available models of predicting the shear deformation of diagonally-cracked reinforced concrete ... -
Finite element analysis of shear deformation in reinforced concrete shear-critical beams
Huang, Zheng; Lü, Zhitao; Tu, Yongming; Blanksvärd, Thomas; Sas, Gabriel; Elfgren, Lennart (Journal article; Peer reviewed, 2017)The objective of this paper was to study the contribution of shear deformation in reinforced concrete (RC) shear-critical beams. A 2D concrete material model based on smeared fixed crack was presented and incorporated into ... -
Freeze-thaw damage evaluation and model creation for concrete exposed to freeze–thaw cycles at early-age
Liu, Dongyun; Tu, Yongming; Sas, Gabriel; Elfgren, Lennart (Peer reviewed; Journal article, 2021)Concrete subjected to freeze–thaw cycles action at early-age will suffer serious physical damage, resulting in degradation of the concrete’s performance. The subsequent curing conditions after early-age freeze–thaw cycles ... -
Mechanical and durability properties of concrete subjected to early-age freeze–thaw cycles
Liu, Dongyun; Tu, Yongming; Shi, Pan; Sas, Gabriel; Elfgren, Lennart (Peer reviewed; Journal article, 2021)Early-age frost damage to concrete used in winter construction or in cold environments negatively affects the development of the hydration process and the performance of the concrete, thereby reducing the service life of ...
