Numerical study on shear strengthening of reinforced concrete (RC) deep beams with and without stirrups using near-surface mounted FRP bars [PDF]

open access: yes, 2020
Near surface mounted (NSM) technique is an emerging technique for increasing the strength of reinforced concrete (RC) members. It is applied to strengthen or repair RC members.

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]

open access: yes, 2017
The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

Structural behaviour of Reinforced Concrete (RC) columns under fire

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract The paper presents a numerical study on the response of RC columns under fire. The numerical studies deal with both: during fire (fire rating) scenario and after fire (residual) scenario. The results highlight the importance of Load-Induced-Thermal-Strains (LITS) for predicting the Fire Rating (FR) of RC columns.

Assessment of RC elements strengthened with NSM FRP rods by experimental tests [PDF]

open access: yesMATEC Web of Conferences, 2020
Near surface mounted (NSM) technique of strengthening with FRP rods inserted in grooves on the concrete cover of damaged RC beams has been improved in recent years. The aim of this paper is the examination of the static and dynamic behaviour of undamaged

Flexural and shear strengthening of RC beams with composites materials: the influence of cutting steel stirrups to install CFRP strips [PDF]

open access: yes, 2009
[Excerpt] Introduction: Experimental [1], numerical and analytical [2] research reveals that as larger is the height of the cross section of Carbon Fiber Reinforced Polymer (CFRP) strip, as more effective is the Near Surface Mounted (NSM) technique for ...

Finite element modeling of steel bar buckling in FRP-confined RC columns [PDF]

open access: yes, 2015
Fiber-reinforced polymer (FRP) confining jackets offer an attractive solution for the seismic retrofit of reinforced concrete (RC) columns. For an accurate prediction of the strength and ductility of FRP-confined RC columns, it is necessary to understand
