Frames generally have fully fixed connections while trusses typically have pin joints. For this reason SkyCiv Truss models all connections as pin/hinge joints (FFFFFR fixity code at the member end to simulate the moment being released about the z-axis). In SkyCiv Frame all connections are treated as fully fixed (FFFFFF fixity code at the member end).

Note: Only SkyCiv Structural 3D software allows users to fully control and customise the member connections.
