초록
Composite piles have been used in ground conditions where conventional piles are unsuitable or uneconomical. They may consist of a combination of timber and concrete pile in Europe. One method of doing this was to drive a steel tube to just below water level, and a concrete pile was lowered down it and driven to the required level where corrosion was susceptible in U.K. Recently, a fiber reinforced polymer (FRP) composite pile was developed to use in many marine locations for piers and waterfront buildings in the USA(Hoy, 1995; Phair, 1997). A steel composite (SC) pile reinforced concrete spun pile with steel tube was also proposed and used for the foundation acting a high lateral earthquake load. Composite piles have been developed and researched to increase lateral resistance or to prevent corrosion in marine structures. In paper, the composite pile consisting of the steel upper portion and the concrete lower portion is proposed and are carried out several tests to confirm the capacity of the pile such as lateral load test, dynamic load tests and bending test. It is noted that the composite pile would be a economical pile being capable of increasing lateral resistance.
