Abstract: In Singapore, sudden changes of bedrock depth and highly variable weathering degrees in residual soils are commonly observed. This study employed the dispersive characteristics of Rayleigh-type surface waves from combined ...

Abstract: A constitutive model that represents soil behavior under a wide range of loading conditions is necessary for the simulation of complex boundary value problems. However, most laboratory tests are interpreted with an assumption ...

Abstract: Based on an extensive in situ shear-wave velocity (Vs) database, this study aims to not only examine the stress-dependent characteristics of in situ Vs from a generalized Vs-stress model [Vs=α×(σc′)β], but also provide ...

Abstract: As industrialization advances, the increase in impermeable areas in urban regions has changed the water circulation system. Hence, many environmental issues such as heat islands and city floods have arisen. To solve this ...

Abstract: The amount and magnitude of absorption and scattering of stress waves in concrete, mainly due to internal friction and aggregate inclusions, may be different when concrete mix proportions vary. In this study, we investigate ...

Abstract: As industrialization advances, the increase in impermeable areas in urban regions has changed the water circulation system. Hence, many environmental issues such as heat islands and city floods have arisen. To solve this ...

Abstract: It is well-known that the performance of Portland cement concrete (PCC) pavement depends, to a great extent, on the support condition under the slab. The Texas Department of Transportation (TXDOT) recognized the importance ...

Abstract: This paper studies the effectiveness of calcium sulfoaluminate (CSA), which has a much lower carbon footprint than conventional ordinary portland cement (OPC), in geotechnical applications which use high water:cement ratios. ...
