도시철도 내진설계기준 주요 내용 검토

Recently "Earthquake Resistance Design Regulations for Subway structures" has been established. It is the first time in our country. In this paper the regulations is reviewed and expalined briefly. Contents for the Performance Based Design Criteria and the estimation method for the design earthquake reponse spectrum in underground structures are reviewed. Earthquake resistance design for the evaluation of liquifaction, boundary spring coefficients for structural analysis modelling and soil response displacements are investigated and described also. Earthquake resitance design details shall be explained.
