【 摘 要 】

The seismic stress-strain soil foundation response needs to evaluate with high quality in geotechnical earthquake engineering design. The stress and strain are controllable in soil foundation design. In the present study, the simulated near-fault ground motion has been applied on the model and the seismic resistance of concrete footing to produce shape and magnitude of seismic stress investigated. The main objective of this study is to understand, the concept of strain energy density dissipation mechanism in geotechnical earthquake engineering. The strain energy has been discussed based on results of numerical analysis and those have been reported in the literature. The results have been found that the strain energy density dissipation mechanism meaningfully effects on concrete foundation stress mechanism production and it leads to produce seismic differential settlement mechanism for concrete footing.
