Solving Two-Dimensional Truss with MATLAB
Solving the truss using the stiffness method.
The steps of solving the truss by the stiffness method:
- Numbering of nodes and elements
- Specifying the length of each element
- Obtaining sin and cosz
- Forming the stiffness matrix of each member
- Forming the total stiffness matrix
- Writing the relationship F = K U in matrix form
- Removing rows and columns that can be removed from the above matrix
- Solve the above matrix and get U or displacements
- Obtaining the stress in each member
- Obtaining support reactions
To use this code, just add the specifications of the truss you want to the Excel file and run the Truss2DD.m file.
Program outputs include:
- Stiffness matrix
- load vector
- Displacement
- Stress
- Reaction
- Truss Shape(black)
- ِDeformed Shape(red)
