Abstract: Optical fiber sensors are emerging as a superior nondestructive means for condition evaluation of civil structures. The ability of an optical fiber sensor to monitor strain distribution in a structural material depends on ...

Abstract: A constitutive relationship for high-strength concrete (6 to 15 ksi) is developed based on the continuum damage mechanics. The bounding surface concept was employed in the formulations of the theoretical model. A comprehensive ...

Abstract: Monitoring of distributed strains provides important information about the behavior of structural systems. However, detection and quantification of cracks while still at micro size levels will play a more-important role ...

Abstract: Assessment of fracture characteristics for cementitious composites subjected to impact loading is important in prediction of structural response and residual capacity under dynamic loading conditions. In the study reported ...

Abstract: A new model for the determination of fracture-mechanics parameters in concrete is developed. Application of this method requires merely knowledge of peak load and peak crack-mouth–opening displacement (CMOD) values. The ...

Abstract: The development and testing of a pseudoductile hybrid fiber-reinforced polymer rod consisting of glass and carbon fibers is described. Two different hybrid forms were considered for the development of the hybrid rods, ...

Abstract: The study presented in this article concentrated on investigating the ductility and characterization of damage in concrete beams post tensioned with hybrid carbon-glass fiber-reinforced polymer (HFRP) composites. The ...

Abstract: The work presented pertains to the development and application of a damage detection method in bridges by use of distributed fiber-optic sensors. It utilizes the dynamic mode of the Brillouin optical time-domain analysis ...

Abstract: A new method for conversion of the distributed strain measurements to crack opening displacements (CODs) in structural elements is introduced. A hybrid approach involving theoretical and experimental strain distribution ...

Abstract: A method is presented for estimating the mode shapes of multispan structures based on the distributed optical fiber strain sensors. The dynamic mode decomposition method was employed to decompose the spatial–temporal strain ...
