DOMINANT FREQUENCY COMPONENT OF SEISMIC WAVE FOR THE DAMEGE OF UNDERGROUND STRUCTURE
|
|---|
| 抄録（英）： |
Two dimensional non-linear FEM analysis and several one dimensional equivalent analyses are performed to investigate the dominant frequency components of a seismic wave for the damage of underground structures. The results show the following. The seismic performance of underground structures is dominated by the relative displacement between the upper and the lower slab. The relative displacement is strongly influenced by the frequency components of an input motion lower than 2Hz. The effect of frequency components higher than 3Hz on the relative displacement is almost negligible.
