‘Portal frame + SM’ provides a stiffness matrix analysis for a 33-node plane frame with 3 degrees of freedom –vertical, horizontal and rotation - access to the stiffness matrix (SM). Rigid or spring supports possible. 4 load cases. Results given for bending, axial and shear forces and graphs for bending moments and shear.
- Input data
- Results for displacements and member forces
- graphs for bending moments and shears
