A total six under reinforced beams with varying concrete cover (25 mm and 30mm) were fabricated and tested. Data presented include the deflection characteristics and cracking behavior. The experiment results compare reasonably well with the current codes of practice. It was observed that a beam ...
Any shortfall of concrete cover less than the project specification requirement can dramatically affect the structure integrity over time, reducing its lifetime. For marine structure projects or any special structures, the concrete thickness measurement is part of the quality control requirement. The ...

beams made with normal strength concrete have covered a wide range of first order beam design parameters, with their results used to verify the generality of various theoretical models. In the present paper, much attention will be devoted to various structural characteristics (such as ultimate ...
It was proven that these failure modes can be avoided by extending the bond length of FRP strips or using U-wraps of CFRP sheets. The stress transfer length of the prestressed-FRP strengthened beam with U-wrap anchorage is approximately 100mm. 展开 关键词: Near surface mounted Prestressed FRP...
