INTEGRATED SOFTWARE FOR STRUCTURAL ANALYSIS AND DESIGN
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.
SAP2000 has a wide selection of templates for quickly starting a new model. SAP2000 includes parametric templates for the following types of structures: Simple Beams, 3D Trusses, 3D Frames, Storage Vessels, Staircases, Dam Structures, and Pipes.
View and manipulate analytical and physical models with great precision. Easily define custom views and developed elevations to view and manipulate complex geometry with ease.
In SAP2000, grids can be defined as cartesian or cylindrical. There is no limit to the number of grid systems in a model and they can be rotated in any direction or placed at any origin within the model.
Plans and Elevations
Plan and elevation views are automatically generated at every grid line to allow for quick navigation of the model. Users can create their own elevation sections by using our Developed Elevation feature.
Interactive Database Editing
Interactive database editing allows users to edit model data in a table view which simplifies the task of making changes to the model. Tables are easily exportable and importable from Microsoft Excel and Microsoft Access.
Engineers have many options when it comes to mesh generation in SAP2000. Simply select the area object and then select the rules for the automatic mesh generator to use.
SAP2000 automatically create joints at structural object intersections or internal joints when meshing structural objects. Joint coordinates and information may be displayed on screen in the model window or in tabular format.
The frame element uses a general, three-dimensional, beam-column formulation which includes the effects of biaxial bending, torsion, axial deformation, and biaxial shear deformations. SAP2000 has a built-in library of standard concrete, steel and composite section properties of both US and International Standard sections.
The cable element is a highly nonlinear element used to model the catenary behavior of slender cables under their own self-weight. Tension-stiffening and large deflection nonlinearity are inherently included in the formulation.
Tendons are easily drawn as independent objects, with geometry specified as straight lines, parabolas, circular curves, or other arbitrary shapes. Tendon loads, including all losses, are easily defined in SAP2000.
The shell element is a type of area object that is used to model membrane, plate, and shell behavior in planar and three-dimensional structures. The shell material may be homogeneous or layered throughout; material nonlinearity can also be considered when using the layered shell.
The solid element is an eight-node element for modeling three-dimensional structures and solids. It is based upon an isoparametric formulation that includes nine optional incompatible bending modes and is useful for modeling objects in which loading, boundary conditions, section properties, or reactions vary by thickness.
A link element may exhibit up to three different types of behavior: linear, nonlinear, and frequency dependent, according to the types of properties assigned to that element and the type of analysis being performed. The following link elements are available in SAP2000: Linear, Multi-linear Elastic, Multi-linear Plastic, Gaps, Hooks, Dampers, Friction Isolators, Rubber Isolators, T/C Isolators, Frequency-dependent Springs, and Frequency-dependent Dampers.
Users can create and apply hinge properties to perform pushover analyses in SAP2000. Nonlinear material behavior in frame elements (beam/column/brace) can be modeled using fiber hinges. This approach represents the material in the cross section as discrete points, each following the exact stress-strain curves of the material. Mixed materials, such as reinforced concrete and complex shapes can be represented.
Spring supports are link elements that are used to elastically connect joints to the ground and can be linear or nonlinear in nature. Nonlinear support conditions can be modeled to include gaps (compression only), multi-linear elastic or plastic springs, viscous dampers, and base isolators.
The wave-loading feature automatically generates loading on the structure resulting from waves, current flow, buoyancy, and wind. Multi-stepped static linear loading can be generated to simulate the wave moving through the structure. In addition, dynamic (time-history) loading can also be generated to include inertial effects as the wave moves through the structure.
SAP2000 can perform both linear static and multi-step static analysis. The linear static analysis of a structure involves the solution of the system of linear equations represented by K u = r. Certain types of load patterns are multi-stepped, meaning that they actually represent many separate spatial loading patterns applied in sequence. These include the vehicle, live, and wave types of load patterns.
SAP2000 dynamic analysis capabilities include the calculation of vibration modes using Ritz or Eigen vectors, response-spectrum analysis, and time-history analysis for both linear and nonlinear behavior.
For small to medium sized structures, analysis can be performed on the fly as you build and modify the model. For each change you make to the geometry, properties, or loading, the structure instantly responds with the new deformed shape, moment diagram, or any other plot of results. It’s like working with a live model, and it is a very powerful tool for conceptual design and for testing “what-if” scenarios.
