Corrosion cracking of reinforced concrete caused by chloride salt is one of the main determinants of structure durability. Monitoring the entire process of concrete corrosion cracking is critical for assessing the remaining life of the structure and determining if maintenance is needed. Fiber Bragg Grating (FBG) sensing technology is extensively developed in photoelectric monitoring technology ...

The behavior of concrete-filled fiber tubes (CFFT) polymers under axial compressive loading was investigated. Unlike the traditional fiber reinforced polymers (FRP) such as carbon, glass, aramid, etc., the FRP tubes in this study were designed using large rupture strains FRP which are made of recycled materials such as plastic bottles; hence, large rupture strain (LRS) FRP composites are enviro...

Post-earthquake observations and laboratory tests reveal the needs for innovative solutions that can enhance concrete compression ductility in boundary elements of special structural walls. This study proposes a new element design by utilizing hybrid fiber reinforced (HyFRC). One full-scale HyFRC is tested uniaxial compared to three conventional are compliant with ACI-318 codes. Results demonst...

The incorporation of reinforcements is a necessity to compensate for the deficiency that concrete presents with its fragile behavior and low deformation capacity. One solutions improve tensile performance addition fiber in random distributions throughout volume. However, this strategy can compromise compressive strength concrete; consequently, purpose study was analyze conventional hybrid reinf...

This paper presents the results of an experimental study to evaluate the damage and failure mode of hybrid-fiber engineered cementitious composite (ECC) panels caused by large projectiles or fragments with the aim towards quantifying the extent to which hybrid-fiber ECC improves the resistance of blast panels against impact loading. Drop weight tests are conducted on full-scale blast/shelter pa...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...
