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.

Loading
Auto-seismic loading according to the ASCE 7-16 code, Korean Building Code (KBC 2016) and IS 1893:2016 code has been added.

Automated response spectrum functions according to the ASCE 7-16, Korean Building Code (KBC 2016) and IS 1893:2016 codes have been added.
Auto-wind loading according to the ASCE 7-16 code and Korean Building Code (KBC 2016) has been added.


Analysis
The effect of reinforcing steel on the axial creep and shrinkage behavior of concrete in columns and walls is now included in the time dependent staged-construction analysis.

A pure event-to-event option has been added for nonlinear static analysis.


Frame Design
Steel frame design according to AISC 360-16 has been added.

Modeling
An option has been added to control the limiting negative stiffness ratio for frame hinges.
