Abstract

Surface waves are not considered directly in the current earthquake resistant design code of the underground lineal structure, because a method for estimating the surface wave as input motion is not established. A procedure for calculating the expected value of peak ground displacement from bedrock motion is presented in this paper; the bedrock motion is converted to Love Nave spectra by the method proposed by the authors, and Love wave spectra is converted to peak ground displacement by the method proposed newly in this paper. Input motions of the underground transmission line is estimated as an example case to compare the axial forces derived by the method and by the current earthquake resistant design code of the underground transmission line. It is confirmed that the structure designed based on the current code is safe against surface waves.

Prediction of Characteristics of Surface Wave for Earthquake Resistant Design

St. Louis, Missouri

Surface waves are not considered directly in the current earthquake resistant design code of the underground lineal structure, because a method for estimating the surface wave as input motion is not established. A procedure for calculating the expected value of peak ground displacement from bedrock motion is presented in this paper; the bedrock motion is converted to Love Nave spectra by the method proposed by the authors, and Love wave spectra is converted to peak ground displacement by the method proposed newly in this paper. Input motions of the underground transmission line is estimated as an example case to compare the axial forces derived by the method and by the current earthquake resistant design code of the underground transmission line. It is confirmed that the structure designed based on the current code is safe against surface waves.
