Abstract: The corrosion resistance of glass-fiber-reinforced polymer (GFRP) rebars makes them a promising substitute for conventional steel reinforcing rebars in continuously reinforced concrete pavements (CRCPs). Studies are conducted ...

Abstract: This paper presents a nondestructive evaluation method to identify the structural stiffness of ceramic candle filters. A ceramic candle filter is a hollow cylindrical structure made of a porous ceramic material used in ...

Abstract: The analysis of stress waves in an acoustic surface waveguide is presented. Elastic wave motions in a circular rod propagating through a rigid circular joint bonded on an elastic half-space were studied. The responses of ...

Abstract: Seven-wire steel strands are widely used in various types of prestressed concrete structures. When a strand is subjected to a tensile force, the traveling time of the stress wave will be affected due to the elongation of ...

Abstract: This paper presents a nondestructive, stress wave technique to evaluate the prestress levels in posttensioned seven-wire strands. Seven-wire steel strands are widely used in various types of prestressed concrete structures. ...

Abstract: The propagation of elastic waves in liquid-core cylindrical acoustic waveguides is studied. The model analyzed represents a liquid-filled tube embedded inside a solid medium. The frequency equations are derived, and ...

Abstract: In this study, the early-age mechanical properties of a concrete mix containing ground granulated blast furnace slag (GGBFS) were investigated and incorporated in a finite-element model. The viscoelastic behavior caused ...

Abstract: The dynamic soil-structure interaction phenomenon involved in a shallow-buried flexible plate under impact loading is investigated both experimentally and numerically. This interaction causes load relief on the buried ...

Abstract: In this paper, the exact solution of the Timoshenko beam vibration frequency equation under free-free boundary conditions is determined with an accurate shear shape factor. The exact solution is compared with a three-dimensional ...
