Abstract

The paper presents an overview of recent advances in earthquake geotechnical engineering with respect to the seismic design of geotechnical structures. The modern principles in seismic design are described along the framework of performance-based design as adopted in the International Standard (ISO23469). With the growing awareness of the need to understand the effect of non-linearity in soils and soil-structure interaction, the paper discusses the highly non-linear response of ground during strong earthquake motions with a peak ground acceleration exceeding 1g, and the highly non-linear behavior of soil-pile interaction, including soil-pile separation. The modern principles in seismic design described in this paper allow a sophisticated approach to deal with the uncertainty. Discussion on this issue is provided through the life-cycle cost approach. The paper also discusses the combined hazards, such as those during the Sumatra, Indonesia, earthquake of 2004, posing a new challenge to seismic design of geotechnical structures.

Performance-Based Design of Geotechnical Structures: Recent Advances

San Diego, California

The paper presents an overview of recent advances in earthquake geotechnical engineering with respect to the seismic design of geotechnical structures.
