 SAP2000
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 Templates built into the interface.
The Advanced Analytical Techniques allow for Step-by-Step Large Deformation
Analysis, Multiple P-Delta, Eigen and Ritz Analyses, Cable Analysis, Tension
or Compression Only Analysis, Buckling Analysis, Blast Analysis, Fast
Nonlinear Analysis for Dampers, Base Isolators and Support Plasticity,
Energy Methods for Drift Control and Segmental Construction Analysis.
Bridge Designers can use SAP2000 Bridge Templates for generating Bridge
Models, Automated Bridge Live Load Analysis and Design, Bridge Base Isolation,
Bridge Construction Sequence Analysis, Large Deformation Cable Supported
Bridge Analysis and Pushover Analysis.
SAP2000 is for everyone! SAP2000 is for every project! From a simple
small 2D static frame analysis to a large complex 3D nonlinear dynamic
analysis, SAP2000 is the answer to all structural analysis and design
needs.
 Here are some reasons why?
For bridge design, SAP2000 automates moving load analysis like no other
software. Lanes are easily offset from beam centerline to consider torque
and other reactions, even with curved and inclined systems. Built-in AASHTO
vehicles with user defined options for truck and train loads. Auto generation
of influence lines and min/max force & moments for all possible permutations
of traffic loads. Several built-in design codes, including AASHTO, for
steel and concrete design. We've heard time and time again from users
that SAP2000 moving load analysis is hands down the best available - spend
10 minutes with the interactive bridge tutorial and see if you don't agree.
SAP2000 enables users to easily apply loads or assign restraints/supports
in skewed directions different from the global axis. Even if you don't
have skewed restraints/supports, but have sloped beams or bracing, SAP2000
analysis results are reported in local directions, making it easy to interpret
the direction of deflections or forces without having to do time consuming,
error prone transformations.
Steel member sizes can be optimized based on strength per design code
with user defined uto select lists of sections. Compare SAP2000 optimization
to manual trial and error, analyzing ne section per member at a time.
SAP2000 shell elements provide unique element formulations which avoid
the 'shear locking' problems found with classical finite elements. The
ability of SAP2000 to output shell forces and moments at each shell joint
which are integrated over the shell thickness, and then sum them, provides
several advantages. First of all, forces & moments from shell joints
can be selected and summed using SAP2000's group joint force sum option
in order to obtain useful results such as base shear and moments, or section
cuts for strength design. SAP2000 stress resultants are reported by joint
per unit of in-plane length.
Meshing options - Most structural programs that offer shell elements
limit the user to meshing the plate/shell into uniformly spaced 2X2, 4X8,
etc. types of meshes. But what if a shell joint load, area uniform load,
or member intersection does not match the joint location or shell area
of the uniformly divided shells? SAP2000 provides options to mesh based
on: 1) grid intersections 2) selected joints on edges as well as 3) uniformly
spaced shells, in order to mesh precisely where is needed. Users can add
gridlines or draw joints on edges to refine the mesh with minimal effort.
SAP2000 constraint options provide unique capabilities to rigidly 'link'
joints which are offset from one another. In addition to rigid diaphragms,
SAP2000 also provides additional constraint types which rigidly transfer
forces and moments from one joint to another in all degrees of freedom,
or in selected degrees of freedom, while accounting for secondary moments
that occur due to the distance between the joint locations (lever arm
effect). This ability to transfer secondary moments differentiates these
constraints from traditional master-slave/rigid diaphragm type of constraints.
This is particularly important when connecting beams with shell elements,
modeling composite behavior, or joint connections offset from an element
centerline which can cause secondary moments. SAP2000 constraint options
become especially critical for accurate reactions in a dynamic analysis.
SAP2000 enables users to review analysis results graphically by clicking
on individual members or joints, or generate output reports. Output reports
can be limited by graphically selected areas, or by pre-defined groups,
by load case/combination. Results can be printed, exported to Excel or
Access database, as well as generation of DXF drawings.
Automated code design beyond the basics - Automatic load combinations
per design code, automatic determination of unsupported lengths, P-M-M
diagrams for capacity ratios, special seismic considerations, and much
more. Review SAP2000 design manuals to see how far SAP2000 has automated
the design process compared to how you're working now.
Advanced analysis - Options for nonlinear base isolators, dampers, gaps,
large deflection, and plastic hinges for pushover analysis. Modal, response
spectrum, linear or nonlinear time history dynamic analysis. No limit
on use of springs, dampers, and other elements in dynamic analysis.
