Abstract

Introduced was a new anti-corrosive method with improved ease of construction, economy, and durability that could be applicable for steel-composite drilled shaft. The feasibility and economy of sea-water-resistant steel was evaluated under the assumption that it was to substitute carbon steel for steel casing of drilled shaft foundation as a load carrying structural member not just as a sacrifice casing, and that anti-corrosive protection measures as required by the domestic standards was applied. Sea-water-resistant steel was found to cost 30% to 55% more, depending on pile diameter and the type of applied anti-corrosive measures, than carbon steel for the service life time of 70 years: 50% to 90% more for 100 years of service life.
