determinate trusses can be analyzed for internal axial forces. Data input is visual
and requires only the minimum definition from the user.
- The overall dimensions
of the truss are established by creating a user-defined grid of joints.
- Truss members
are defined by using a mouse to draw lines connecting the desired joints. The
software checks the members as they are defined to ensure that the truss idealization
assumptions are satisfied (i.e., members connected only at the joints)
- Supports and loads
are also defined with mouse movements. The software checks to allow at least
three support constraints and to accept loads only at the joints.
- Labeling of joints
is performed automatically. Angles of truss members are computed and displayed
as the truss is created.
- The analysis results
are shown on the truss. Tension members, compression members, and zero force
members are each indicated by a different color.
- Optionally, normal
stresses can be computed for the truss members, or given a stress limit, the
required area for each member can be computed from the results of the truss
