    Abstract: The traditional method of disposing of tire debris is now a huge worldwide problem and presents serious environmental risks. Because of this, using waste tires in concrete not only lowers its density but also guarantees an economical and environmentally responsible alternative for the building sector. However, because of their superior ductility an... Show More

    Abstract: Differential settlements of foundation can result in the excessive relative rotation angles between bar-wrapped cylinder concrete pressure pipes (BCCP), which may cause the failure of joint structures. This paper presents experimental and numerical methods for investigating mechanical properties of pipe joints under different relative rotation angl... Show More
