Abstract: This paper investigates the influence of bond slip on crack spacing in reinforced concrete. A bond-link element is used to account for the influence of the bond slip between the concrete and the reinforcing steel. Following ...

Abstract: This paper investigates the minimum and maximum crack spacings in concrete pavements from the energy viewpoint and explores mechanisms that control spacing. An analytical model, which is composed of two cohesive cracks and ...

Abstract: A method to integrate the nonlinear partial-differential equations of motion of a cantilever beam capable of coupled flexural-torsional vibrations is presented. The technique uses spatial finite-difference approximations ...

Abstract: In the setting of thermomechanical transient analysis of concrete using isotropic damage, the writers noted the consistent occurrence of spurious bifurcations of the deformation field, for thermal and mechanical loading ...

Abstract: A plasticity model using a strain‐rate formulation is presented to describe the uniaxial response of concrete when subjected to combined thermal and mechanical actions. The total strain rate is resolved into three individual ...

Abstract: A method for determining the uncertainty in the location of a cross-correlation peak is derived and two examples are examined. When a cross-correlation peak location is used in transit time ...

Abstract: The technical and economic feasibility of producing specific gas products by the catalytic gasification of biomass is presented in this paper. Active catalysts were developed for generation of ...

Abstract: Bench-scale reactor tests are under way at Pacific Northwest Laboratory to develop a low temperature, catalytic gasification system. The system, licensed under the trade name Thermochemical ...
