SAP2000 for Oil and Gas
Latest release: SAP2000 15.1.0/1

SAP2000’s sophisticated analytical methods and design algorithms directly address the Oil and Gas industry’s structural engineering requirements. Analytical features include the ability to easily capture rotational acceleration due to pitch, roll and yaw; perform simple linear or complete nonlinear snap-through buckling analyses; compute frequency-domain response for harmonic and non-harmonic periodic loading; calculate power-spectral density response; apply automated wave loading and API 4F wind loading; pushover analysis and much more. The implementation of the API 4F, API 2A (offshore structures) and Norsok N-004 (offshore structures) design codes allows the engineer to optimize designs with greater accuracy and speed, including punching shear checks. Structural models are very easily created through the integrated 3D SAP2000 environment where users can model all structural geometry, complex built-up sections, loading, and analytical components. Spreadsheet capability is integrated within the graphical environment for creating or modifying the model as well as viewing or processing the analysis and design results. Customizable reports can be produced that include graphical and tabular data. The Open Application Programming Interface (OAPI) can be used to develop special-purpose plug-in tools or to link with in-house programs.

Rotational Acceleration Loads

  • In addition to translational acceleration loads, SAP2000 allows users to apply rotational acceleration loads to easily capture pitch, roll, and yaw effects. These accelerations can be applied as static and/or dynamic loads.

Cable Elements with Large Displacement Options

  • SAP2000 offers true nonlinear cable elements with catenary behavior and large displacement analysis. Coupling this with dynamic analysis enables engineers to capture true inertial effects along with the complex changes in behavior as members forces change from tension to compression and vice versa during various lift or launch stages.

API 4F

  • For offshore and drilling structures, SAP2000 offers automated API 4F wind load generation and comprehensive design code unity checks. Wind loads can be applied from any angle relative to the structure and local axis of the members. Loads are automatically modified to include the effects of shielding, cladding, and ice.

 

  • The API 4F design code check accounts for the difference between shielded and unshielded wind loads on an element-by-element basis per the design specification.

Design Code Checks

  Comprehensive design code checks for steel and/or concrete frames are available for a multitude of international design codes, including: API 4F, AISC, CSA S-16 Canadian, Eurocode, and more. Code-dependent lateral loads based upon code parameters can be conveniently generated for API 4F wind, ASCE 7-05 wind (open frame or building structures), IBC2006 seismic, NBCC 2005 wind and seismic, and other international standards.

Import from StruCAD*3D

  • Input files for StruCAD*3D (Engineering Dynamics Inc., formerly Zentech) can be imported directly into SAP2000 Version 14.

Buckling Analysis

  • SAP2000 offers linear Eigen buckling and nonlinear snap-through buckling analysis, either of which may be necessary when designing tall mast structures.

 

  • Nonlinear buckling analysis also includes the effects of large displacements.

Offshore Module

  • 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.

P-Delta Analysis

  • SAP2000 nonlinear P-delta analysis automatically includes both sway (“large Delta”) and local (“small delta”) member deformations, satisfying the requirements of the AISC Specifications (13th edition) and other design standards.

Advanced Dynamic Analysis

  • Dynamic time-history analysis can include the effects of linear or nonlinear soil boundary conditions. Soil conditions can be modeled using compression-only springs, gap-friction behavior, and/or multi-linear plastic behavior specified by P-Y and T-Z curves.
  • Automatic generation of sinusoidal time-history functions is available for modeling unbalanced rotating loads. Transient and steady-state response can be calculated for the displacements, velocities, accelerations, forces, and stresses, including step-by-step and max/min values.
  • SAP2000 can perform periodic time-history analysis for non-harmonic loading, such as reciprocating machinery, operating at any frequency. * Arbitrary load assignments can automatically be converted to mass.
  • SAP2000 steady-state harmonic analysis considers the entire “sweep” of machine-speed frequencies all in one load case. Loading may be specified with different phase angles. Supports and links may be given frequency-dependent properties, enabling consideration of radiation damping and complex support systems. Frequency plots of displacement, velocity, acceleration, force, and stress response can be produced at any phase angle, or for the resultant magnitude.

Wave Loading

  • View resultant wave velocity and acceleration graphically with color coded plots, or through output tables which can be brought into Excel.

Section Designer

  • SAP2000 has an integrated Section Designer makes it easy to define composite and built-up section properties

 

  • The user can see details of complex built-up section geometries using the rendered extruded view option of SAP2000.

 

  • Using the concepts of insertion point and cardinal point, frame members may be modeled using centerline, top of steel, bottom of steel, or any other arbitrary reference lines. This allows the convenient alignment of members with a know datum. The effect of the eccentricity upon the connections is automatically accounted for. Shell elements may also be offset from the reference surface. Combining frames and shells offset from a common set of connection nodes is an effective way to model composite behavior.

 

  • A layered shell is available to model composite materials. Each layer may have different isotropy and orientation, so that fiber-wrapped and other built-up constructions can be represented.

Prestressed Modal and Eigen Buckling Analysis Options

  • Modal analysis and Eigen buckling analysis can be based on a prestressed condition, such as due to thermal, gravity, pressure, and or other loads.

 

  • P-delta and tension-stiffening, as well as other nonlinear effects, may change the modal or Eigen buckling behavior, and the effect of both prestressed and unstressed conditions can be considered simultaneously in the same model.

 

  • ASCE 41 and other design standards have codified the practice of analyzing seismic loads based on prestressed modal analysis.

Center of Gravity

  • SAP2000 can automatically determine the center of gravity (CG) of the structure based on selfweight and user selected assigned loads.

 

  • If piping, cladding, equipment or other gravity loads were applied as assigned loads, users have the option to include those assigned loads in the CG calculation and report.
