Finite element method and fiber model were used to calculate the load-carrying capacity of specimens. Based on experimental theoretical analysis, simplified calculation for this kind member is proposed. It indicates that finite result relatively small, accords well with result. Circular reinforced concrete members covered steel tube presents both characteristics filled member, showing higher gr...

Abstract At present, the need to make use of industrial waste materials is increasing due their harmful effects on environment. In present work, behavior hybrid reinforced T-Beam with partial substitution recycled rubberized concrete studied. The finite element modeling by using ANSYS version 15 program. It contains also all required steps needed create models that were prepared study beams (RR...

Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

This article presents the 3D computational modeling method for reinforced concrete structures. An example of calculation beam, using Finite Element Method in SCAD++ following proposed algorithm, is given. Results comparison to analytical model with selected reinforcement presented. For concrete, solid Elements are used and beam elements reinforcement. The formed AutoCAD AutoLISP, which creates ...

The chloride corrosion of reinforcing steel in reinforced concrete (RC) structures is a significant reason for premature deterioration and failure of RC structures in aggressive environments such as Persian Gulf region. This is one of the most important sources of engineering and economic problems in developed countries. So, the repair and maintenance of RC structures exposed to corrosive envir...

During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls.  A few rein...

In recent decades, the application of fibre-reinforced polymer (FRP) composites for strengthening structural elements has become an efficient option to meet the increased cyclic loads or repair due to corrosion or fatigue cracking. Hence, the objective of this study is to explore the existing FRP reinforcing techniques to care for fatigue damaged structural steel elements. This study covers the...
