Abstract: Pseudo-static analysis is one of the most common and simplest approaches used to assess the seismic stability of reinforced-soil retaining walls. Despite the importance of the equivalent seismic coefficient as the key ...

Abstract: A review of liquefaction case histories shows that sand deposits containing some fines were common in past liquefaction events. While current liquefaction mitigation measures are mostly applicable to clean sands or open ...

Abstract: A series of reduced-scale model tests was conducted on helical soil-nailed walls (HSNWs) under vertical surface loading to evaluate the effect of length, pattern, and inclination of nails on lateral pressure distribution ...

Abstract: A series of undrained cyclic triaxial tests were carried out on loose sand specimens, including encased and non-encased granular columns, to evaluate the cyclic behavior and liquefaction resistance of the ground improved ...

Abstract: Analytical solutions are presented for laminar fully developed flow in micro-/minichannels of hyperelliptical and regular polygonal cross sections in the form of compact relationships. The considered ...

Abstract: Alkali activated slag (AAS) concrete can be considered as a more environmentally friendly alternative to conventional concrete. The presence of cracks in the concrete matrix can have major impacts on its mechanical properties ...

Abstract: A computational investigation is carried out to study the effect of oscillations on vortex generation and vorticity flux for flow over a deforming arc airfoil. The flow is laminar, incompressible, and twodimensional at ...

Abstract: Most deck-truss bridges have been designed and constructed without seismic resistance considerations; as a result, their members, connections, and frequently their substructure are not sized and detailed to provide the ...

Abstract: A companion paper has demonstrated how deck-truss bridges can be retrofitted by converting the end cross-frames and lower end panels adjacent to the truss supports into special ductile panels. However, the design of such ...

Abstract: Fuzzy membership functions are implemented in the multistage optimization technique to improve its performance for the minimum weight design of truss structures of fixed topology. First, a large truss is split into several ...
