STUDY ON AXIAL ANALYSIS OF UNDERGROUND STRUCTURES IN SEISMIC DESIGN

Abstract

The conditions of soil properties at different locations should be considered for axial deformation analysis of underground structures, because they are spatially extended. Though various analyzing methods are proposed, the author focuses on stationaly wave model, and presents some results in this report, such as the effect of boundary conditions and the simplification of response of bi-linear soil spring model. Recently, performance design method is needed for underground structures, then it is important to develop axial deformation analysis which can pursuit large deformation and structural damage easily. The method proposed in this paper is useful for these aims.
