| Abstract: |
Near fault earthquakes have been distinguished for their probability of having pulse-like characteristics with higher velocity time history amplitudes. This could be significant for retaining walls found in bridges and nuclear power plant buildings. Several two-dimensional numerical models of an embedded wall-soil system were developed in Abaqus® by varying the wall rigidity and friction coefficient between the wall and soil. The friction coefficient was varied from 0 to 0.5. In one model, the wall is very rigid and in the other the wall is flexible with original modulus of elasticity. Seismic pressures in the soil-wall system are evaluated. The analyses are performed considering non-pulse and pulse-like motions that match a narrow-band modified target spectrum for a moment magnitude of 7.70. The objective is to study how the soil-wall system is affected by pulse-like seismic events and how the contact conditions affect this response. |
