Enumeration definition
ConstantDescription
RIGID_JOINED_MEMBERA member with capacity to carry transverse and axial loads, i.e. a beam. Its actual joints may be rigid or pinned. Typically used in rigid frames.
PIN_JOINED_MEMBERA member with capacity to carry axial loads only, i.e. a link. Typically used in trusses.
CABLEA tension member which is able to carry transverse loads only under large deflection.
TENSION_MEMBERA member without compressional stiffness.
COMPRESSION_MEMBERA member without tensional stiffness.
USERDEFINEDA specially defined member.
NOTDEFINEDA member without further categorization.
