Here I developed a MATLAB code for solving beam problems using Finite Element Technique with the ability of plotting deformed shape. Results of this code include nodal displacements; axial forces, bending moments, and shear forces for members; reaction forces at supports.

Below are some of the results:

three-story, two-span bending frame with dead load and lateral load.

 one-story, one-span bending frame with lateral load.

Results are verified with Abaqus and analytical methods.

I wrote a finite element code (FEM Program) for two-dimensional analysis of elastic body using MATLAB programming language.
Here is a video of the results + its verification with Abaqus:

4-node elements ,4 Gauss points for numerical integration are used;.
