View article: Joint kinematics and sealing capacity assessment of ductile iron pipes under abrupt transverse ground movements
Joint kinematics and sealing capacity assessment of ductile iron pipes under abrupt transverse ground movements Open
Joint kinematic behaviour, i.e., joint rotation and axial translation, can partially help pipelines to accommodate abrupt ground movements, and cause leaking if joint service limit is exceeded, even without any structural failure. Kinemati…

Numerical study of earth pressures on rigid pipes with tire-derived aggregate inclusions Open
Rigid pipes under high embankments are often installed using the induced trench technique by introducing a compressible zone above the pipe. Made from discarded tires, tire-derived aggregate (TDA) has a high compressibility and is resistan…
