simdesign.rcmrf.bnsm.baselib.node

This module provides the class used to represent any structural node within the BNSM layer. Unlike other classes in baselib, this class does not require abstraction.

class simdesign.rcmrf.bnsm.baselib.node.Node(tag, coordinates, masses=None)[source]

Bases: object

Structural node representation in the BNSM layer. It provides methods to define the node in the OpenSees domain and to export equivalent Python and Tcl commands.

Parameters:

tag (int)
coordinates (List[float])
masses (List[float])

tag

Unique identifier of the node.

Type:: int

coordinates

Node coordinates [x, y, z].

Type:: List[float]

masses

Nodal masses associated with each degree of freedom: [Mx, My, Mz, RMx, RMy, RMz].

Type:: List[float]

nodal_mass

If True, masses are assigned directly to the node in OpenSees.

Type:: bool, default=True

add_to_ops()[source]

Adds the node object to OpenSees domain.

The node is created using the ops.node command. If nodal_mass is True and at least one mass component is non-zero, nodal masses are assigned using the -mass option.

Return type:: None

to_py()[source]

Gets the python command to construct the node object in OpenSees.

Returns:: Python command for constructing the node object in OpenSees.
Return type:: str

to_tcl()[source]

Gets the Tcl command to construct the node object in OpenSees.

Returns:: Tcl command for constructing the node object in OpenSees.
Return type:: str
