Experimental study on shear strengthening of shear critical RC beams using iron-based shape memory alloy strips

Engineering structures, 2019
Shape memory alloys (SMAs) have been introduced into structural engineering in recent years. This paper presents research results about developing a new methodology to actively strengthen reinforced concrete (RC) beams by low-cost iron-based SMA strips ...

Postcracking Compliance Analysis of RC Beams

Journal of the Structural Division, 1979
An analytical model for postcracking compliance of rectangular reinforced concrete beams under combined torsion, bending, and transverse shear is established using the skew bending theory. The case of small transverse shear and the case of large transverse shear are treated separately based on widely accepted failure modes.

Behaviour of strengthened RC T-beams

Magazine of Concrete Research, 1995
Twelve reinforced concrete T-beams were each strengthened in shear by the incorporation of additional stirrups in a thickened section cast using non-shrink grout. Another beam was strengthened by thickening the existing section only, without any additional reinforcement.

Impact resistance of RC beams with reinforcement corrosion: Experimental observations

, 2020
Reinforcing steel corrosion is a serious problem that may negatively impact the safety and serviceability of reinforced concrete (RC) structures. To properly maintain and manage RC structures with corroded reinforcement, it is necessary to clarify the ...

Anchorage of composite laminates in RC flexural beams

Structural Concrete, 2010
This paper focuses primarily on flexural strengthening with pre-cured fibre-reinforced polymer laminates applied on reinforced-concrete beams with different anchoring devices, both chemically and mechanically applied. The results showed that the ultimate load of the strengthened beams was 35–80% higher than the control beam, depending on the type of ...

Effect of the correlation of steel corrosion in the transverse direction between tensile rebars on the structural performance of RC beams

, 2020
Reinforcement corrosion is highly nonuniform and spatially distributed in reinforced concrete (RC) structures. Since RC members are reinforced with multiple rebars, corrosion of one rebar might affect another rebar in the transverse direction, thereby ...

Study on the flexural strengthening effect of RC beams reinforced by FRP grid with PCM shotcrete

, 2020
Recently a new repair and retrofit method of reinforced concrete (RC) members that uses fibre-reinforced-polymer (FRP) grid with polymer-cement-mortar (PCM) shotcrete has been proposed.
