A Detailed Evaluation of Eurocode and ISO Methodology on Earthquake-Resistant Geotechnical Designs

Abstract eng:
This paper presents the design concepts of Eurocode 7, Eurocode 8 and ISO 23469. Detailed comparisons are made between Eurocode 8 Part 1 and the ISO code. Conclusions are drawn on their relative merits. A simple strip foundation design example is shown to illustrate the methodology of Eurocode 8. The performance of this design is also evaluated using the PLAXIS Dynamic software package. The results of the dynamic analyses show that the seismic design of simple foundation needs to be performance-based. The Life-Cycle Cost concept mentioned in ISO 23469 is also briefly introduced as a possible performance-based seismic design method for the future.
