ABSTRACT

Geotechnical design practice has been gradually changing in recent years from Allowable Strength Design (ASD) to Limit State Design (LSD), known as Load and Resistance Factor Design (LRFD) in the United States and Canada. Geotechnical resistance factors are greatly influenced by the site geology and the design and construction practice, and it is important to incorporate local ASD experience and practice accumulated over many decades in developing geotechnical LRFD codes. Foundation design and construction practice in Korea is quite different from that of other countries, and the Korean geotechnical community realized the need of developing our own LRFD codes.
