Numerical Evaluation of Dynamic Earth Lateral Pressure on Basement Walls in Cohesionless Soils (A Case Study of Iranian Earthquakes)

Various earth-retaining structures are extensively used in different civil engineering projects. Using the results of experimental and numerical modeling, effect earthquake loading on distribution earth lateral pressures basement walls was investigated. The UBCHYST constitutive model performed simulations, using 12 centrifuge dynamic tests, a calibration process conducted to obtain proper input parameters for models. Based results, some correlations between increment coefficient pressure (ΔKae) free-field peak ground acceleration (PGAff) were established. stiff flexible walls. In end, verified by examination major earthquakes that occurred Iran plateau. showed proposed ΔKae-PGAff precise enough applied design
