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. defining a new problem. Mass is used for the inertia in dynamic analyses, and for calculating the built-in acceleration loads. Notable meshing features include the ability to merge independently defined meshes among frame, shell and solid objects, coordinate tessellation with object orientation, and observe material boundaries to establish effective aspect ratios.
