Abstractfulltext

Seismic performance of concrete block retaining wall with concrete backing was evaluated by the shaking table test and compared for acceleration and displacement at various nodes with the theoretical calculation by finite element method. Two dimensional elasto-plastic dynamic analyses were performed by using recorded Kobe NS component acceleration as input motion for both cases. Structural inspection helps to alleviate secondary disaster after an earthquake. A regular inspection of retaining walls in the vicinity of inhabitants is necessary not to allow the situation of retaining walls to worsen by the natural agencies. Proposed manual for inspection will be helpful for the inspection and rating the level of risk which will inspire residents for regular upkeep of retaining walls. Finally, a newly developed non-destructive Surface Wave Method (SWM) for the evaluation of stiffness of retaining wall is introduced.
