BEHAVIOR OF FREE-ACCESS FLOOR DURING SEISMIC EXCITATION BY THREE-DIMENSION INPUT WAVE AND HORIZONTAL ONE-DIMENSION INPUT WAVE

Fundamental study on evaluation method for seismic resistance of free-access floor

Abstract

Using one typical kind of free-access floor specimen, the behavior during seismic excitation by three-dimension input wave was compared with that by horizontal one-dimension input wave. As the conclusion, it was obtained that damage by real three-dimension seismic excitation could be estimated based on the result of the excitation test using one-dimension input wave, which was selected from two horizontal axes as the direction containing the maximum acceleration. The result of this study will be applied to establish the simple method to evaluate the seismic resistance of free-access floor, which will consist of one-dimension excitation test.
