要旨 |
In this paper, damage of underground RC ducts having interaction with liquefied soil foundations is discussed by using nonlinear dynamic finite element analysis coupled with soil. The simulation is performed in both drained and undrained conditions to clarify the effect of liquefaction on the response of structure. The results show ground liquefaction greatly deteriorates the soil skeleton stiffness and results in the reduced damage to RC structures even though large displacement occurs. It implies that the required ductility of RC ducts can be moderated if the liquefaction risk is high. |
