During input the restaint let say G/Z ( From the layout my client going to cast a concrete block on the pipe as represent a G/Z support ) , do i need to remove the bi-linear restraint or retain the bi-linear restraint ?
2. May i know the coefficient of friction between FRP pipe surface and rubber sheet & concrete between rubber sheet .
