CAESAR II

Pipe Stress Analysis software

Overview

Since its introduction in 1984, CAESAR II from Intergraph Corporation has become the world’s most widely used pipe stress analysis software and is considered the industry’s de facto standard. CAESAR II is a complete pipe stress analysis software program that allow quick and accurate analysis of piping systems subjected to weight, pressure, thermal, seismic and other static and dynamic loads. It can analyze piping systems of any size or complexity. CAESAR II is unique, incorporating calculation methods and analysis options not found in any other program.

Input & Modeling Capabilities

CAESAR II input capabilities have revolutionized the way pipe stress engineers approach flexibility analysis. Input and modeling capabilities include

Interactive Graphics

Let you walk around your model, taking you just one step short of holding the model in your hand. CAESAR II supports single-line, volume, wire frame and rendered graphics.

Data Input

CAESAR II makes it easy to input and display all the data needed to accurately define a piping system analysis model.

Wide Selection Of Restraint Types

Provides the widest range of support types for boundary conditions.

• Anchors with or without displacements
• Single or double acting translational
• Single or double acting rotational
• Translational with bi-linear stiffness
• Snubbers
• Guides and limit stops
• Bottomed-out springs
• Tie rod assemblies
• Gaps and firiction
• Connecting nodes for nodal interdependence
• Large rotation rod supports

Extensive databases

Provides a comprehensive material database with temperature dependent allowable stresses. Includes valves and flange databases with built-in length and weight information. Provides the ability to add your own data.

Structural steel modeling

Helps you set realistic boundary conditions, not idealistic ones. CAESAR II includes structural steel database from many international standards.

Extensive FRP (Fiberglass) Pipe Capabilities

Includes two piping codes specifically for fiberglass reinforced plastic pipe plus vendors data for modeling and analysis.

Other Input & Modeling Capabilities Include

• Either Y or Z as vertical
• “Undo/Redo” input correction
• User-tailored units
• Cold spring elements
• Bend/intersection Stress Intensification Factor (SIF) calculator and library
• Multiple job batch processing
• Automatic buried pipe modeling
• Thermal bowing

Static Analysis Capabilities

CAESAR II begins a static analysis by recommending load cases necessary to comply with piping code stress requirements. CAESAR II allows you to analyze piping and structural models together, and you can observe the effect of the non-linear pipe-structure interaction both graphically and numerically. Static analysis capabilities include:

• Automatic, Comprehensive Error Checking
• Extensive Spring Hanger Selection Options
• ASCE Wind Load Generation
• Nozzle Flexibilities and Stresses
• Equipment Load Checks
• Flange Leakage and Stresses
• Fatigue Analysis and Cumulative Usage Report
• Offshore Piping Analysis

Dynamic Analysis Capabilities

CAESAR II guides you through the specification or acquisition of data needed for dynamic analysis. Dynamic analysis begins with the specifications of the dynamic input data such as lumped masses, imposed vibration, and spectrum definitions. Dynamic analysis capabilities includes.
• Mode Shape and Natural Frequency Calculations
• Harmonic Forces and Displacements
• Shock Spectrum Analysis and Independent Support Motion (Including Anchor Movements)
• Force Spectrum Analysis
• Model Time History Analysis
• Animation of Dynamic Response
