Abstract: The tensile behavior of reinforced concrete and clay unit masonry was studied by conducting a series of 33 direct tension tests on instrumented specimens. The effect of the steel reinforcement ratio was the principal ...

Abstract: Preformed pavement polychloroprene compression seals were analyzed using dynamic shear rheology and numerical analysis to assess the feasibility of using these techniques to develop an improved methodology for designing ...

Abstract: A series of early‐age creep tests was conducted on mass‐concrete mixtures to be used in the construction of locks and dams. Tests were conducted to determine creep at ages of loading from 18 h through several days. While ...

Abstract: The classical Westergaard idealization of the rigid pavement system assumes that the slab-on-grade can be modeled as a thin elastic plate on a bed of springs. Implicit in this assumption is the Kirchhoff (or thin) plate ...

Abstract: Runway rubber removal is a maintenance function employed to ensure safe landing areas for aviation operations. Rubber deposits accumulate on runway areas where aircraft tires touchdown and braking occurs. This tire-rubber ...

Abstract: Shear walls are subjected to biaxial in-plane stresses when resisting seismic or wind loadings. Vertical tensile cracking reduces the compressive strength of walls in a direction normal to the tensile strain. This has been ...

Abstract: The most widely used terrorist tactic is the improvised explosive device, which can range in size from hand-held to truck-size. Most casualties and injuries sustained in such an attack are not caused by the blast itself, ...

Abstract: During 2 days in October 1994, 4-month-old concrete on a runway developed extensive spalling along transverse joints. Damage was extensive, limited to transverse joints; was located in trafficked areas only; and developed ...

Abstract: Recent terrorist attacks indicate the improvised explosive device as the choice terror tactic. Over the past decade, the U.S. Department of Defense has encouraged and sponsored research toward developing methods of reinforcing ...
