BASIC STUDY OF VERTICAL GROUND MOTION FOR SEISMIC DESIGN

Abstract

This paper investigates the characteristics of vertical ground motions obtained by the 1995 Hyogoken-Nanbu Earthquake and at Oharai array observation site in recent several years. After the survey of several design codes concerning the vertical ground motions, observation records treated in this paper are compared to the response acceleration spectra proposed by Building Rresearch Institute in MOC, Japan, and some recommendation are proposed.
