Abstract: Concrete is a composite material composed mainly of water, sand, aggregate, and cement. The characteristics of high attenuation of concrete for ultrasound degrade the performance of ultrasonic testing (UT), especially when ...

Abstract: A crack condition evaluation method is proposed that identifies the damaged state of deteriorated reinforced concrete (RC) girders on bridges directly on-site. This nondestructive testing approach is based on stress wave ...

Abstract: The flexible interface model is adopted in this paper to analyze the three-dimensional (3D) elastic constitutive relationships, together with the local stress and strain distributions within constituent layers of an ...

Abstract: Tendon corrosion and the leakage of water through the grouting voids are important contributors to the degradation of prestressed concrete (PC) bridges. Therefore, leakage inspections are beneficial in determining whether ...

Abstract: To install the continuous welded rail (CWR) on the viaduct, it is necessary to consider the accumulated axial force owing to temperature difference and the additional force of the rail exerted by the track-bridge expansion ...

Abstract: The behavior under static loading of fiber-reinforced plastic (FRP) retrofitted reinforced concrete beams, possessing a high chloride content and rebar corrosion, was studied both experimentally and analytically. The test ...

Abstract: Developing an appropriate and efficient inspection pattern for an unknown bridge substructure is a critical issue for bridge engineers, contractors, and bridge agencies. This paper introduces a two-phase near-surface ...
