EFFECT OF PHASE CHARACTERISTICS OF SEISMIC WAVE ON DAMAGE OF BUILDING AND PILE FOUNDATION(Structures)

Abstract

This report presents an effect of phase characteristics of seismic wave on earthquake damage of building and pile foundation. Seismic responses of a soil-pile-structure system are calculated for six waves whose phase characteristics are different. Soil non-linearity caused by soil strain and liquefaction is considered in calculations. Coefficients of variation about structure and pile damage for six waves are estimated. The non-linearity of liquefaction makes large the coefficients of variation because non-linear responses are influenced by phase characteristic of seismic wave.
