    How does pile driven system affect concrete?How does pile driven system affect concrete?However, when the area of reinforced concrete section is increased, the soil resistance would also increase. Pile driven system features such as speed, stroke, ram weight, and real performance of pile driving system on the construction site would influence pile drivability to a certain extent.What is Pile Drivability? Factors Influencing Drivability Evaluation of strength recovery of repaired steel pipe piles Mechanical Properties of Fillet Weld Joints by Evaluation of strength recovery of repaired steel pipe piles

    This paper presents a series of experiments on fourteen different assemblies of fillet weld joints produced by both underwater and in-air welding. Mechanical properties of underwater fillet welds in terms of strength, ductility, and failure modes are investigated in this study. Weld profiles, hardness distributions, and metallographic features of underwater welds are also examined.

    Minimum Yield Strength - an overview ScienceDirect Topics

    Steel pipe piles should have a minimum yield strength not less than 35,000 psi. Structural steel piles should conform to ASTM A36, ASTM A572, and ASTM A588. Steel pipe piles should conform to ASTM A252. Steel-encased cast-in situ concrete piles should conform to ASTM A252, ASTM A283, ASTM A569, ASTM A570, or ASTM A611. What is the yield strength of steel pipe?What is the yield strength of steel pipe?The most common industry standard for steel line pipe is the API 5L. This standard specification covers both normal (grade B with yield strength of 35,000 psi/240 MPa) and high-strength steels (X42 to X80 with yield strength of 42,000 psi/290 MPa to 80,000 psi/550 MPa).
