Specification of joint characteristics (Input Table)

Data description/conditions:

JOINTREF:

Reference name from input table PIPES

Unique name in list

TYPE:

Type of joint

Prescribed names: Socket-L, Socket-S, Spigot-L, Spigot-S, Sleeve-L, Sleeve-S, Ball, Hinge or Tight.

(Socket-L: socket-spigot connection, socket at start of joint element without stop
Socket-S: socket-spigot connection, socket at start of joint element with stop
Spigot-L: socket-spigot connection, spigot at start of joint element without stop
Spigot-S: socket-spigot connection, spigot at start of joint element with stop
Sleeve-L: double socketed coupling sleeve without stop
Sleeve-S: double socketed coupling sleeve with stop
Ball: ball hinge free rotations in all directions
Hinge: pin hinge free rotation around one axis, the pin axis
Tight: connection with resistance to tensile strain, no free translations and rotations
 
Start of joint element is the lower node number.)

x-C:

Clearance in axial socket direction in case of compression

0. / Undefined ¹

x-T:

Clearance in axial socket direction in case of tension

0. / Undefined ¹

MaxRot:

Maximum possible free lateral rotation

0. and < 180. / > 0. and < 180. / Undefined ²

Rotdir:

Angle between the plane of rotation and the horizontal plane

0. and < 360. / Undefined ³

OVALtype:

Indication of ring stiffness of joint construction

Prescribed names: Stiff (no ovalisation possible), Normal (stiffness of continuous pipe), Free (stiffness of free pipe end)

(If Undefined (empty), the Free condition is applied.)

 

¹ Undefined for TYPE = Ball, Hinge or Tight


² > 0. for TYPE = Ball and Hinge; Undefined for TYPE = Tight


³ Value required if TYPE = Hinge, else Undefined
