This package can process structures of 2D rigid joint frames.

It can read a CSV file with values of details of rigid joint frame and processes it to extract the structure details.

The package can display in a Web page the details of the processed structure.

2 dimensional rigid jointed frame analysis class

* Frame2DClass * * Class Inheritance * [FEMSolver] * -> [Frame2D] * [FEMSolver] is base class and includes several matrix operation for the standard FEM solutions. * [Frame2D] is a class for the FEM solution process and include data structure of 2 dimensional rigid jointed Frame. * [Frame2D] use [CSV] class for handling csv file to store and retrieve associated arrays; * Solution process run for the loaded truss to analyse deformations, reactions and element forces. * Multiple load cases will be solved simultaneously. * Html result tables are generated during the process. * Model of 2d Frame can be generated within class by assigning values to variables. * Or model can be created by loading CSV file. * Model csv file is very simple comma separated text file in-wich the properties of FEM element, boundary conditions and loads are written.
