Description

Author

Win Aung Cho

This class can analyse pin truss using the finite element method.

It can read a CSV file with values of pin truss and performs analysis of the parameters of the three dimensional structure.

The class can display on a Web page the nodal displacements, element forces and the reaction.

A pin truss is a piece that can be used to join different parts of a physical object like for instance a piece of furniture.

Ideally, to make the piece of furniture hold itself with robustness, it is necessary to perform calculations to design the pin truss.

This class uses the finite element method to perform such calculations to give an idea of the robustness of a given pin truss.
