EARTHQUAKE OBSERVATION OF DEEPLY EMBEDDED BUILDING STRUCTURE
|
�´˜^�i‰p�j�F
Earthquake observation of the deeply embedded building structure in the suburbs of Tokyo has been continued on a large scale for the purpose of investigation of dynamic soil-structure interaction behavior. It is found that by comparison between the transfer functions of the dynamic lateral pressures and those of the velocities of the soil, the both shapes of the spectra at around the first natural frequency closely coincide. In the dynamic lateral pressures, no predominance in a frequency range higher than the first natural frequency is observed. Dynamic lateral pressures obtained by the response analysis of two dimensional FEM are coincident to these of observation results.
