“…A detailed description of the analytical model for R/C jacketed members is presented in the last section of this article. The same approach has also been implemented after the necessary modifications for predicting the response of thin reinforced self-compacting three-jacketed beams (Chalioris et al 2014). Moreover, Tsioulou and Dritsos (2011) developed an analytical model for predicting the flexural capacity of beams strengthened by the addition of a concrete layer in the tension or compression zone.…”

With the continuous developments of civil engineering practices in general and structural engineering in particular, engineers have been investigating the rehabilitation/strengthening techniques of existing structures to save them and/or increase their load capacity by raising the efficiency of the structural elements of existing buildings such as beams and columns. This technique used for different purposes such as in increasing the lifetime of these structures, adapting with the change of functionality of the building, and to overcome the error design. The objective of this study is to investigate the effect of changing some properties of reinforced concrete jacket u-shaped which used for strengthening reinforced concrete (RC) beams. This study focused on increasing the load capacity of beams in existing buildings. The effect of changing yield strength, concrete strength, rebar size, and thickness of RC jackets on the load capacity of beams have been investigated aiming at identifying the best practices in this regard using Finite Element Method (FEM)-based numerical analysis utilizing ANSYS software. Moreover, reinforcement stress is discussed. The results of the numerical analysis have verified experimentally utilizing previous research. It is noticed that some of the proposed changes for RC jackets contribute in improving of performance for U-concrete jacketing technique to be a more effective technique to strengthen the existing beams which shall help engineers in practical use in the field. The thickness of the RC jacket has been changed to 10 cm rather than 2.5 cm with the same characteristic in Case.g. Boundary Condition and Applied LoadCharacteristics of the boundary condition and applied load can be summarized in the following points and in (Fig. 2): 1. The beam self-weight was taken into consideration in this numerical modeling.

“…In addition, the efficiency of the SFRC for shear strengthening is directly related to the use of steel stirrups. Chalioris et al [36] investigated the use of thin reinforced self-compacting concrete (SCC) for strengthening of conventional shear-critical RC beams through experimental and analytical studies. e strengthened beams exhibited increased strength and ductility in addition to favourable failure behaviours.…”

e repair and strengthening of reinforced concrete members are very important due to several factors, including unexpected increases in load levels and/or the damaging impact of aggressive environmental conditions on structural concrete members. Many researchers have turned to using materials for the repair and strengthening of damaged structures or the construction of new concrete structural members. Ultrahigh-performance fibre-reinforced concrete (UHPFRC), characterized by superior structural and durability performance in aggressive environmental conditions, is one of the materials that have been considered for the repair and strengthening of concrete structural members. e repair or strengthening of concrete structures using UHPFRC needs a thorough knowledge of the behaviour of both the strengthening material and the strengthened concrete structure at service load conditions, in addition to an understanding of the design guidelines governing the use of such materials for effective repair and strengthening. In this study, the recent issues and findings regarding the use of UHPFRC as a repair or strengthening material for concrete structural members are reviewed, analysed, and discussed. In addition, recommendations were made concerning areas where future attention and research on the use of UHPFRC as a strengthening material needs to be focused if the material is to be applied in practice.
