To study the effect of local corrosion prestressed steel strands on shear failure mode and bearing capacity concrete beams, unilateral in four post-tensioning (PC) beams are corroded, test PC performed. Moreover, a simplified calculation method for with diagonal bars is proposed considering cross-sectional reduction bars, degradation mechanical properties, damage concrete. Results shows that cr...

This paper presents an experimental investigation of bond-strengthening hooks as a new method to increase bond strength along flexural reinforcing bars in reinforced concrete (RC) beams. The proposed method attempts to increase confining stiffness around the flexural bars by placing U-shaped hooks and to prevent premature bond splitting failure. Ten specimens with different numbers and sizes of...

In this study, the simulation of simple bending problem is performed using an example of cantilever beam which is an important structural member. The author executed numerical simulations for simple and cracked cantilever beams using finite element stiffness method, analytical beam theory, finite element package (ANSYS) and then verified results with code generated in C++ language. In conclusio...

FRP (Fiber Reinforced Polymer) Bar reinforced coral concrete beam is a new type of structural member that has been used more and widely in marine engineering recent years. In order to study predict the flexural performance CFRP beams, rigidity, crack morphology failure mode were studied detail. The results show under condition similar reinforcement ratio, rigidity significantly lower than ordin...
