Abstract: Analytical studies have shown repeatedly that soil stiffness plays a dominant role in influencing the structural behavior of buried culverts in loading environments; however, the relative effect of the soil-model formulation ...

Abstract: This paper presents a method to analyze and evaluate buried culverts and cut-and-cover tunnels for seismic loading in addition to standard static loading from dead and live loads. Using CANDE-2007, a plane-strain finite-element ...

Abstract: A time‐dependent plasticity model for rocks and soils based on Perzyna's elastic/viscoplastic theory is presented, wherein the plasticity yield function is patterned after the inviscid cap model developed over the last ...

Abstract: Circumferentially slotted bolt hole connections, a new concept for corrugated metal culverts, have proven to be effective in reducing thrust stress (ring compression) in deep embankment installations. Pragmatically, this ...
