From its 3D object based graphical modeling environment to the wide variety of analysis and design options completely integrated across one powerful user interface, SAP2000 has proven to be the most integrated, productive and practical general purpose structural program on the market today. This intuitive interface allows you to create structural models rapidly and intuitively without long learning curve delays. Now you can harness the power of SAP2000 for all of your analysis and design tasks, including small day-to-day problems. Complex Models can be generated and meshed with powerful built in templates. Integrated design code features can automatically generate wind, wave, bridge, and seismic loads with comprehensive automatic steel and concrete design code checks per US, Canadian and international design standards. Advanced analytical techniques allow for step-by-step large deformation analysis, Eigen and Ritz analyses based on stiffness of nonlinear cases, catenary cable analysis, material nonlinear analysis with fiber hinges, multi-layered nonlinear shell element, buckling analysis, progressive collapse analysis, energy methods for drift control, velocity-dependent dampers, base isolators, support plasticity and nonlinear segmental construction analysis. Nonlinear analyses can be static and/or time history, with options for FNA nonlinear time history dynamic analysis and direct integration. SAP2000 v16 offers a single unified user interface for modeling, analysis and design. Autocad-like snap tools for fast and easy model creation Zoom controls Standard views XY, XZ, YZ, 3D Live multiple graphical windows that make for easy navigation of complex models Active planar view is automatically highlighted in the 3D view window Developed elevation option to define custom views, including "unwrapping" cylindrical and irregular geometry Define working planes for creating and editing complex geometries Coordinate Systems/Grids Cartesian Cylindrical Generalized Grid Sytems - allows for a system comprised of arbitrarily defined grid lines. Models can have multiple coordinate systems/grids which can be rotated in any direction.
