# Connector uniaxial behavior

 Connector uniaxial behavior: can be defined in any connector with available components of relative motion by specifying the loading and unloading behavior; can be specified for each available component of relative motion independently; can define separate response in the tensile and compressive directions; can exhibit nonlinear elastic behavior, damaged elastic behavior, or elastic-plastic type behavior with permanent deformation upon complete unloading; can have an unloading response specified; and can be specified as dependent on constitutive motions in several local directions. The local directions for each connection type (as described in Connection types) determine the directions in which the forces and moments act and in which the displacements and rotations are measured. The following topics are discussed:
