In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

For a reinforced concrete beam subjected to fatigue loads, the structural stiffness and bearing capacity will gradually undergo irreversible degeneration, leading to damage. Moreover, there is an inherent relationship between the stiffness and bearing capacity degradation and fatigue damage. In this study, a series of fatigue tests are performed to examine the degradation law of the stiffness a...

This paper presents a method for detecting defects in reinforced concrete structures by using the method of active infrared (IR) thermography. Non-destructive testing using infrared (IR) thermography consists of thermal stimulation of the object of interest and monitoring of the surface temperature variation during the transient cooling or heating process. The paper includes short descriptions ...

Corrosion of steel in concrete is one of the major problems with respect to the durability of reinforced concrete structures. The majority of concrete structures perform well even after a long period of use in normal environments. However, there are various reinforced concrete structures important for our infrastructure, especially bridges and buildings, which exhibit premature damage due to en...

one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

Fiber reinforced concrete is a composite material consisting of mixtures of cement, fine aggregate, coarse aggregate and fibers. The fiber reinforced concrete exhibits better fatigue strength and increased static and dynamic tensile strength and compressive strength. In this project, the strength of fiber reinforced concrete was investigated partial replacement of cement with rice husk ash and ...

Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The te...

7 Corrosion of reinforcing steel in concrete can alter the interface between the steel and concrete and 8 thus affects the bond mechanism. This subsequently influences the behaviour of reinforced 9 concrete structures in terms of their safety and serviceability. The present paper attempts to 10 develop a numerical method that can simulate the behaviour of reinforced concrete walls subjected 11 ...

Reducing waste material plays an essential role for engineers in the current world. Nowadays, recycled materials are going to be used in order to manufacture concrete beams. Previous studies concluded that the currently proposed formulas to predict the flexural and shear behavior of the reinforced concrete beams were not appropriate for those manufactured by recycled materials. This study aims ...
