the soil as the tube is withdrawn. These types of piles are expected to provide high skin friction and end
bearing resistance.
Table 1-3. Steel Pipe Pile Specifications.
LENGTH
12 - 36 M (40 - 120 FT)
MATERIAL
ASTM A36 FOR CORE
SPECIFICATION
ASTM A252 FOR PIPE
ACI 318 FOR CONCRETE
DESIGN
62 MPA (9 KSI); HIGHER STRESSES PERMITTED IF PILE LOAD
STRESSES
TESTS ARE PERFORMED AND EVALUATION CONFIRMS SATISFACTORY
OF PIPE
RESULTS
83 MPA (12 KSI) IF THE PILE IS END BEARING ON ROCK AND IF
THE PILE IS EXPECTED TO PENETRATE THROUGH SOIL DEPOSITS
WITHOUT OBSTRUCTIONS
DRIVING
0.9 YIELD STRENGTH OF THE STEEL Fy
STRESSES
217 MPA (31.5 KSI) FOR ASTM A252, Fy = 241 MPA (35 KSI)
279 MPA (40.5 ksi) FOR ASTM A252, Fy = 310 MPA (45 KSI)
DESIGN LOADS
