The use of steel bars as reinforcement under certain conditions for concrete structures is not preferred, since steel is subject to corrosion. One of the good alternatives to steel bars is Fiber Reinforced Polymer (FRP) rebars. FRP composites are gaining acceptance due to high strength/stiffness to self-weight ratio and corrosion resistance. In this paper, the experimental program consists of four rectangular short columns subjected to eccentric loading. Out of these four rectangular short columns, two columns were reinforced with conventional steel and other two columns with GFRP bars. This paper describes the experimental study conducted to investigate the behavior of short columns subjected to eccentric loading when changing the spacing of transverse reinforcement.
Structural deterioration is a major problem faced in the field of civil engineering. The major reasons for damages are non-engineered construction, improper execution, and wear and tear. Under such conditions, construction is not advisable. Many researchers have subsequently found many new ideas and attempts in which the use of Fiber Reinforced Polymer (FRP) has provided more benefits in strengthening the element without increasing the element's own weight. Nowadays, FRP is increasingly being used in all types of reinforced concrete elements such as beams, columns, slabs, etc. In this paper, GFRP strips are used to strengthen the member. The new attempt will be the application of GFRP strips in number of layers. This paper presents the results based on the analysis of the slabs using ANSYS software. The materials used for this analysis are RC slab with and without GFRP lamination. The slab size is 1500 mm x 900 mm x 100 mm. in which one slab will be laminated by GFRP strips in three layers of same size used for analysis. The results of the analysis clearly show that the use of GRP laminates in three layers in the RC slab significantly increases the strength compared to a conventional slab.
Fatigue is one of the principal modes of failure to be considered in the design of components and structures subjected to repetitive types of loads. The stress intensity factor for the support structures of offshore wind turbines must be evaluated depending on how long the structure can last for future prediction. This study reviewed literatures on fatigue life evaluation of high strength steels used in the support structures of floating offshore wind turbines. The study provides preliminary support for a proposal for a new code provision under the Indian Standard Code for fatigue and fracture testing.
Glass fiber reinforced polymer (GFRP) are considered to increase the lifespan of concrete structures. GFRP shows many important and necessary properties such as low weight to strength ratio, non-corrosive, high fatigue strength, and high tensile strength, crack pattern and crack width, load-deflection curves, etc. RC deep beams are highly resistant to bending failure and therefore have improved flexural performance. This study reviewed the literature on the shear behavior of deep beams strengthened with GFRP sheets. This study, in future will extend preliminary support for new method of section reinforcement in element design. In this paper, shear strengthening with various techniques with the application of FRP has been presented. This study represents preliminary support for proposing a new shear strengthening technique during the design of the member.
Recent RC beam structures are constructed with openings to accommodate pipes and utility ducts Research is being actively carried out on RC beams with web openings and their various types. This paper aims to compile and review the publications on the structural behavior of RC beam openings with and without strengthening techniques. Various features and characteristics will be discussed including the types of openings and their specification along with their structural behavior of RC beams.
