This module conatin my functions for openseespy and you can find the doucumentation using shift+Tab key after their name.

Packages and Functions that Are presented are here with their usage Description:

• AutoModeler (SubPackage)

• TimeHistories (SubPackage)

• dynamic (SubPackage)

  • LAT2 : Function for importing acceleration data from *.AT2 PEER Files.
  • RspSpc : Function for calculating Linear Response Spectrum for any Time History.
  • SDFTHA : Function for calculation the displacement response history of a SDF under any time history acceleration.

• modeling (SubPackage)

  • ElePerPend : Function that Provide a vector that is perpendicular to the line from first defined point to the last defined point.
  • eleAxialForce : Function That return the Axial force of the defined element.
  • MultiEl : Function That draw any number of elements alog defined nodes. This function also returns middle point/s NodeTag/s and their corresponding coordinates. There is an option that by this option User Can specify that end connection be pinned or fixed!
  • GmTVector : Function that return the Geometric Transformation Vector of any element using only one Parameter. For more information Review This: https://github.com/BijanSeif/My-Opensees-Jupyter-NoteBooks/blob/main/Auto%20Geometric%20Transform%20Function%20(GmTVector).ipynb

How to use it:

1- Install it : pip install topspy (for windows)
2- In your python code import it:

• For dynamic subpackage: import topspy.dynamic as bjd
• For modelling subpackage: import topspy.modeling as bjm

3- Using bjd or bjm you have access to mentioned function.

Example of using the functions:

• AutoModeler (SubPackage)

• TimeHistories (SubPackage)

• dynamic (SubPackage)

  • LAT2 :
  • RspSpc :
  • SDFTHA :

• modeling (SubPackage)

  • ElePerPend : bjm.ElePerPend(1,5) Using Node Numbers (Node 1 and Node 5) , bjm.ElePerPend(a,b) Using Node Coordinate (a and b are the coordinate list of node 1 and node 5)
  • eleAxialForce : Axial1,Axial2=bjm.eleAxialForce(eleTag) using element Tag number the axial force of the element is presented in Axial1, Axial2.
  • MultiEl : bjm.MultiEl(4,5,5,elep,0) #Define 5 elements with elep properties from node 4 to node 5 with no buckling shape and in a direct line. bjm.MultiEl(4,5,5,elep,0,'Yes',1e9,10) The last 'Yes' cause that generated element be 2 head pinned using zero length Element with Rigid Stiffness equal to 1e9 or any other user value with NewMaterialTag equal to 10!. (ATTENTION: it is very important that user don't define any previously used tag for NewMaterialTag)
  • MultiElEQDOF :
  • GmTVector : vec=bjm.GmTVector(Node1,Node2,Theta) Using Node Coordinate (Node1,Node2 are the coordinate list of node 1 and node 5) and Theta is the cross section rotation angle according degree and the result (vec) is the Geometric transformation vector.
