SEPARABLE STEEL PIPE PILE FOR SMALL HORIZONTAL DISPLACEMENT

摘要

Disclosed is a separable steel pipe pile for reducing horizontal displacement. According to the present invention, the separable steep pipe pile for reducing horizontal displacement includes: a short pile supporting a load of a structure by being driven into the ground in a vertical direction; and a circular steel pipe having larger inner diameter than the outer diameter of the short pile and driven into the ground in the vertical direction, wherein the inner surface encloses the outer surface of the short pile. The circular steel pipe is formed to be assembled by being separated in the vertical direction, and a horizontal force applied to the short pile is transmitted to the circular steel pipe after the horizontal force is dissipated to a compressive force on the ground between the short pile and the circular steel pipe. According to the present invention, the separable steel pipe pile improves a horizontal support force and an inner structural force and, therefore, improves usability and safety allowance by reducing the horizontal displacement. The separable steel pipe pile for reducing horizontal displacement induces ductile fracture even if the horizontal force of a design load or greater is applied.
