INTEGRATED SOFTWARE FOR STRUCTURAL ANALYSIS & 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.

Features and Advanced Analysis (Selected)

Built-in Frame Sections
SAP2000 has a vast variety of different frame section templates incorporated. User can choose a section template, change the dimensions and it is ready to be used in the model. Standard steel sections from around the world are also available in SAP2000 installation folder which can be imported if it is required.



Section Designer
SAP2000 has a built-in section designer which lets user model any customized section they may need to be analyzed or designed.



Advanced Meshing
Meshing is an easy task in SAP2000. All types of elements can be meshed effectively with few clicks. Not only conventional physical meshing is available but users can use internal meshing in which the actual meshing is assigned as a property and can be modified at any time without the hassle of re-merging elements.
Another, unique feature is innovative "Auto Line Constraint". This technology enables users to force mis-matched meshing to behave as a continuous mesh.




Linear/Nonlinear Springs & Links
SAP2000 has many different spring and link elements available for users to accurately represent the behavior of a structure.

This includes linear, multi-linear elastic, multi-linear plastic, gaps (compression only), hooks (tension only), dampers, friction isolators, rubber isolators, T/C Isolators, frequency-dependent springs and frequency-dependent dampers.




Response Spectrum and Time History Analysis
Response-spectrum analysis in SAP2000 is a statistical type of analysis for the determination of the likely response of a structure to seismic loading. Response-spectrum analysis seeks the likely maximum response to these equations rather than the full time history. SAP2000 also permits the user to specify a time history analysis.

Two methods of Time History Analysis:
-Modal Time History
-Direct Integration Time History




Buckling Analysis
-Linear buckling (bifurcation) modes of a structure can be found under any set of loads.

-Multiple buckling modes can be found, each giving the mode shape and the buckling factor of safety.

-Multiple sets of loads can be considered. Buckling modes can be found for the structure at the end of any staged construction case or any nonlinear static or dynamic analysis.

-Nonlinear buckling analysis is also available considering P-delta or large-deflections effects. Snap-through buckling behavior can be captured using static analysis with displacement control.

-Dynamic analysis can also be used for modeling buckling, including follower-load problems.

-Linear and nonlinear buckling analysis can be combined for the greatest flexibility in understanding structural instabilities.

P delta Analysis(Large and Small Displacement)
The P-Delta effect in SAP2000 refers specifically to the nonlinear geometric effect of a large tensile or compressive direct stress upon transverse bending and shear behavior. A compressive stress tends to make a structural member more flexible intransverse bending and shear, whereas a tensile stress tends to stiffen the member against transverse deformation.

Pushover Analysis
SAP2000 has the ability to perform a pushover analysis
-FEMA 273/ATC-40 hinge and fiber hinge option based on stress-strain
-Nonlinear layered shell element enables users to consider plastic behavior of concrete shear walls, slabs, steel plates and other area finite elements in the pushover analysis.
-Force-Deformation relations for steel and concrete hinges; Modal, uniform, or user defined lateral load patterns; Capacity spectrum conversions; Effective damping calculation; Demand spectrum comparisons; Performance point calculation; Summary reports including plastic hinge deformations

Staged Construction
SAP2000 has the advanced option of incremental construction sequence modelling and loadings. Structures can be analyzed for the effects of staged construction, including changing support conditions, section properties, and the adding and removing of temporary shoring.

Nonlinear effects can be considered such as large deflections, yielding, and gap opening and closing. Tendons can be jacked in multiple stages, and cables automatically tightened to target tensions. Multiple construction sequences may be analyzed in the same model and compared or enveloped.

A Gantt-chart scheduler is available for easy definition of staged-construction load cases.




Time Dependent Creep and Concrete Shrinkage
In SAP2000, Time-dependent creep, shrinkage, and strength-change effects can be included.

-Long term deflections due to creep and shrinkage can be computed along with staged sequential construction analysis.

-Time dependent material properties based upon the 1990 edition CEB-FIP code and user defined curves are used to compute creep strains.

Offshore Features
The Offshore module offers the API 2A and Norsok N-004 design checks, which include checks for joint-can punching shear. The module also includes Airy, Stokes 5th-order, and cnoidal wave theory options. Water currents can simultaneously load the portions of the structure below the water line with automated corrections for marine growth as a function of depth, drag and inertia effects, and buoyancy.

The user can view resultant wave velocities and accelerations graphically with color coded plots or produce output tables of the values that can be exported to Excel.




Advanced Options

In SAP2000, 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. Here is a quick summary of the different types of analysis capabilities in SAP2000.
