Using Finite Element method for Pile-Soil Interface (through PLAXIS and ANSYS)

  This study investigated the pile-soil interaction and its effect on the pile settlement and shear stress in the interaction zone. The impact of loading on the pile displacement was explored applying Mohr-Coulomb as well as Hard-soil behavior laws. First, the modeling proposed by the PLAXIS Bulletin (No. 16) was duplicated in which Hard-soil behavior law was taken into consideration. Next, the modeling took...

Effects of curing conditions on high strength concrete

  Compressive strength of high strength concrete (HSC) cubes cured in water and air (uncured) were investigated at different ages and free water/cement (w/c) ratio. Tensile strength of the HSC cylinders was also determined at 90 days for uncured and water cured specimens at different w/c ratios. Compressive strength decreases were recorded for all the ages tested for uncured specimens compared to water cured...
