Drafting

Many drawing and drafting utilities are built into CSiPlant to enhance the engineer's modeling experience including automatically creating elbows/reducers/Tees and generating multiple supports/links at any given point.

Acceleration Loading

Acceleration loading in CSiPlant can be applied in both translational and rotational directions. Acceleration loads can be applied as static or time history.

Automatic Code Based Loading

CSiPlant will automatically generate and apply seismic and wind loads based on various domestic and international codes.

Dynamics

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.

Ritz Vector

Ritz vector modal analysis can provide a better basis than eigenvectors when used for response-spectrum or modal time-history analyses. Ritz vectors yield better results as they are generated by taking into account the spatial distribution of the dynamic loading, whereas natural mode shapes neglect this.

Response Spectrum

Response-spectrum analysis determines the statistically likely response of a structure to seismic loading. This linear type of analysis uses response-spectrum ground-acceleration records based on the seismic load and site conditions, rather than time-history ground motion records. This method is extremely efficient and takes into account the dynamical behavior of the structure.

Time History

Time-history analysis captures the step-by-step response of structures to seismic ground motion and other types of loading such as blast, machinery, wind, waves, etc. Analysis can use modal superposition or direct-integration methods, and both can be linear or nonlinear. The nonlinear modal method, also called FNA for Fast Nonlinear Analysis, is extremely efficient and accurate for a wide class of problems. The direct-integration method is even more general, and can handle large deformations and other highly nonlinear behavior. Nonlinear time-history analyses can be chained together with other nonlinear cases (including staged construction) addressing a wide range of applications.

Buckling

Buckling can be a design concern in a number of different piping applications including jacketed piping analysis, bowing due to thermal gradient, GRP and plastic piping, rack piping with intermediate anchors, and tall vertical risers among other design scenarios. Using both Eigen buckling and nonlinear large displacement buckling analysis options, CSiPlant makes it convenient for engineers to check for buckling during design.

Nonlinear Load Sequencing

CSiPlant offers unlimited nonlinear load sequencing, also known as path-dependent loading, which considers the order of the loading. Since friction acts in different directions during startup vs. shutdown and other load states, sequenced loading, including sequenced thermal loading and unloading, is often needed to determine worst case reactions and stresses.

Center of Gravity (CG) Calculations

Weight of equipment, cable trays and other items may be assigned as a distributed load or concentrated point loads in the analysis model. CSiPlant enables users to select which loads to include in a Center of Gravity (CG) case and multiple CG cases can be defined and evaluated in the same analysis.

Deformed Geometry

Users can display deformed geometry based on any load or combination of loads, as well as animations of modes.

Pipe Frame Forces/Stresses

Display of pipe/frame forces and stresses can be based on load case, load combination, or modal case. Users can show resultant forces and  stresses on any component in any direction. Control the stress contour appearance by showing undeformed, deformed, or extruded shapes, with or without loading values.

Tabular Output

CSiPlant has the ability to display  tables for all input data, analysis results, and design results. Tables support sort, cut, copy, and paste for use in other programs. Print or save tabular data to Access, Excel, Word, HTML, or TXT.

Comprehensive Integration

CSiPlant allows for integration between piping stress and structural analysis programs. Import detailed SAP2000 structural analysis models into CSiPlant and auto-connect to the piping stress model for coupled nonlinear analysis and design. Import geometry from CII neutral file.

SAP2000 Interoperability

The model import from SAP2000 to CSiPlant is comprehensive and includes load assignments, frame sections and local axes, releases, grids, supports, mass definitions for static seismic and dynamic analysis cases, and other assignments and definitions. Reactions at pipe support locations from the coupled analysis in CSiPlant can be selectively exported back into SAP2000 with options to filter by pipe section and load case. Reactions from SAP2000 can then be automatically exported into SAFE for concrete foundation design to integrate foundation analysis and design with analysis of the structure and piping.
