Brillouin scattering-based distributed optical fiber (OF) sensing technique presents advantages for concrete structure monitoring. However, the existence of spatial resolution greatly decreases strain measurement accuracy especially around cracks. Meanwhile, the brittle feature of OF also hinders its further application. In this paper, the distributed OF sensor was firstly proposed as long-gaug...

As a preliminary study for the erection of floating structures using high performance concrete, this paper examines the bond characteristics between concrete and the reinforcing bar. Since the floating structure is constructed in aquatic environment, corrosion of the reinforcing steel is likely to develop more prematurely than in onshore structure in case of concrete cracking. A solution to thi...

Change in the mechanism of post corrosion bond behavior was investigated a previous experimental study by analyzing deformations concrete using digital image correlation (DIC). Using their DIC data, this focuses on local strain non-uniformity reinforcing bar during uniaxial tensile test due to effect rib height reduction and layer. The results show that, below tip is higher than that flat part ...

Concrete cover is the distance from the surface of the concrete to the surface of the reinforcing bars embedded in the concrete. Ensuring sufficient concrete cover is critical for the durability of some concrete structures subject to poor environment during their service life. Concrete cover can be measured using covermeters. In this paper, some factors affecting cover measurement were briefly ...
