The nodes are connected by a single section object to represent the force-deformation relationship for the element. =================================== =========================================================================== ``eleTag`` |int| unique element object tag ``eleNodes`` |listi| a list of two element nodes ``secTag`` |int| tag associated with previously-defined Section object ``vecx`` |listf| a list of vector components in global coordinates defining local x-axis (optional) ``vecyp`` |listf| a list of vector components in global coordinates defining vector yp which lies in the local x-y plane for the element. (optional) ``rFlag`` |float| optional, default = 0 * ``rFlag`` = 0 NO RAYLEIGH DAMPING (default) * ``rFlag`` = 1 include rayleigh damping =================================== =========================================================================== .. seealso:: `Notes `_
