DEVELOPMENT OF SEISMIC RESPONSE ANALYSIS OF GROUND MOTION WITH ATTENTION TO CONTINUITY OF SOIL IMPEDANCE IN THE VERTICAL DIRECTION
|
抄録（英）：
A seismic response analysis of level ground was investigated. An existing type of analysis has revealed that a hard ground is more vulnerable to a strong motion than a soft deposit. Since this is against the empirical knowledge, the method of analysis was carefully reviewed. Consequently, it was detected that the discretization produces an unrealistic discontinuity in soil impedance at the interface between adjacent layers and elements. The discontinuity reflects the seismic energy unfavorably. Finally, a new type of dynamic analysis was made, by which the above-mentioned problem is solved.
