In the truss example, select the lower-left hand units, and is used for the mass in the three translational directions. For example, if the nodes of a ramp and a wall do not match up, SAP2000 will internally connect all mismatched meshes using the algorithm to act as a zipper between the elements.

Click on grid intersection lines to define joints. Staged construction is a type of nonlinear analysis in SAP2000 that is allows you to define a sequence of stages wherein you can add or remove portions of the structure, selectively apply load to portions of the structure, and to consider time-dependent material behavior such as aging, creep, and shrinkage. However, do this with caution.
