Abstract: A stiffness matrix and nodal load vector of a beam element on a two‐parameter elastic foundation is developed for concentrated loads, concentrated moments, and linearly distributed forces. The formulation is based on the ...

Abstract: Construction of new highway embankments in urban areas often requires building over existing underground utilities and lifelines. Embankments constructed over such utilities often induce substantial additional earth pressures ...

Abstract: The fundamental solution for the stresses induced in a semi-infinite isotropic homogeneous elastic medium by a concentrated point load applied normally to its plane surface is extended to an optimally designed rectangular ...

Abstract: Analysis and mathematical solutions are presented for a torsionally loaded pile embedded in two-layered soil deposit assuming elastic behavior. Soil shear modulus is assumed to be constant in each layer or to vary linearly ...

Abstract: The unprecedented increasing cost of steel coupled with the superior mechanical and anticorrosion properties of fiber-reinforced plastic (FRP) creates a huge opportunity for FRP pipes to take the market share of steel and ...

Abstract: Tapered piles are used in place of cylindrical piles for their improved geotechnical performance. When tapered piles are subjected to axial dynamic loading, as is the case with machine foundations, an appropriate theoretical ...

Abstract: Lightweight materials such as expanded shale/clay/slate or tufts and slag are used in the construction of rigid culverts to mitigate high earth loads and settlements. However, the cost of using lightweight aggregate can ...

Abstract: Experimental investigations reported in the literature have shown that pile foundations exhibit nonlinear behavior when subject to dynamic axial service loads. The nonlinear characteristics are attributed to soil remolding, ...

Abstract: The theoretical models currently reported in the literature idealize a uniformly tapered pile as a step-tapered pile to facilitate dynamic analysis. The step-taper idealization produces approximate solutions, which become ...
