Modeling and Responce of Retaining Wall Subjected to Strong Ground Motions
Modeling and Responce of Retaining Wall Subjected to Strong Ground Motions
This research explores the seismic response of a flexible retaining wall, designed on a construction site in the city of Sofia, Bulgaria. Time-history analyses were carried out using the finite element modeling. The FEM models were created with Plaxis 2D software. The dynamic behaviour of structure and soil is investigated for a set of real accelerograms. A package of amplitude and integral parameters of the earthquakes is analyzed for each accelerogram. Several strong ground motions whose characteristics are compatible with the geological conditions and frequency parameters of the soils on the construction site were selected. For the purpose of soil-structure interaction analysis the retaining structure is modeled as a linear elastic element. The specific non-linear behaviour of soils is modeled by using the complex constitutive laws HSsmall. According to the results from the performed solutions a comparative analysis is developed. The influence upon the seismic response of structure and soil of varying strong ground motion parameters is considered.
