A DFT study on corrosion mechanism of steel bar under water-oxygen interaction
, 2020Corrosion of steel bar is a major problem influencing the long-term performance of reinforced concrete structures. It is known that both oxygen and water involve in the initiation of corrosion of steel bars and determine the formation of the final ...

Abstract Cold-finished steel bars are carbon and alloy steel bar products (round, square, hexagonal, flat, or special shapes) that are produced by cold finishing previous hot-wrought bars. by means of cold drawing, cold forming, turning, grinding, or polishing (singly or in combination) to yield straight lengths or coils that are uniform

Performance of mechanical steel bar splices using grouted couplers under uniaxial tension
, 2020In this study, grouted couplers were used to connect steel bars as an alternative approach to the conventional steel bar lapping method. The aim is to avoid bar congestion problems and to reduce the required quantity of steel bars in order to achieve the

Bolted beam-to-column connection with buckling-restrained round steel bar dampers
, 2020In the design of steel building frames, comprehensive consideration is required to determine beam-to-column connections because their characteristics largely influence the performance of the whole frame.
