Arch model analysis
A plane strain arch model analysis with optional pins at crown and foundations and optional spring supports using a stiffness matrix based on 3 degrees of freedom at each joint – vertical and horizontal deflections and 1 rotation. Loading is by joint forces in 2 directions or nodal moments.
- Input data for geometry, pins, springs and arch properties
- loading input
- results summary for axial and shear forces and moments
- matrix parameters and full set of results
- verification using 3-pin arch.
