Enhancement effect of calcium carbide residue and rice husk ash on soft soil: Small-strain property and micro mechanism

Journal of Materials Research and Technology
The resource utilization of calcium carbide residue (CCR) and rice husk ash (RHA) is helpful to save resources and alleviate environmental pollution. In this research, CCR and RHA were used to modify soft clay, and the resonant column test was conducted ...

Effect of the soil-structure interaction on performance assessment of the energy-based cumulative damage index in concrete reinforced frames [PDF]

Journal of Structural and Construction Engineering, 2016
In most of the conventional design methods, the soil beneath the structure is assumed to be rigid, but this assumption is not true in reality. Up to now, many studies have been performed concerning the interaction effect on the structure response but the
