SAP2000 represents the most sophisticated and user-friendly release of the SAP series of computer programs. When initially released in 1996, SAP2000 was the first version of SAP to be completely integrated within Microsoft Windows. It features a powerful graphical user interface that is unmatched in terms of ease-of-use and productivity. Creation and modification of the model, execution of the analysis, and checking and optimization of the design, and production of the output are all accomplished using this single interface. A single structural model can be used for a wide variety of different types of analysis and design. 3 The SAP name has been synonymous with state-of-the-art analytical methods since its introduction over 30 years ago. SAP2000 follows in the same tradition featuring a very sophisticated, intuitive and versatile user interface powered by an unmatched analysis engine and design tools for engineers working on transportation, industrial, public works, sports, and other facilities. 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. From a simple small 2D static frame analysis to a large complex 3D nonlinear dynamic analysis, SAP2000 is the easiest, most productive solution for your structural analysis and design needs. 4 SAP2000 Levels and Features Physical Modeling Features Basic Plus Advanced Ultimate Model joint size limit 1500 Unlimited Unlimited Unlimited All drafting and model generation features 3D line and area objects 3D solid objects Database of all standard hot rolled steel, aluminum, and cold formed sections Section Designer for specialized sections Interactive database spreadsheet editing Analytical Modeling Features Basic Plus Advanced Ultimate Meshing tools Automatic mesh generator Automatic edge constraint technology for mismatched meshes 2D and 3D frame element Tendon element Cable element Catenary cable behavior Shell element Nonlinear layered shell element Moment curvature curve and PMM interaction surface for arbitrary fiber sections Coupled spring element Plane-stress, plane-strain and solid of revolution (Asolid) elements Solid element Linear link element with stiffness and damping Automated panel zone element Nonlinear link elements: gaps, hooks Nonlinear link elements -
