Integrated Engineering Software, Inc. Creators of high-quality structural analysis software and structural design software. Click image to return to the home page.

AnalysisGroup is a powerful tool for solving six common analysis problems.

  • Rectangular mat footings (multiple column or wall loads)
  • Flat rectangular plates in bending (walls, floors, with openings)
  • Shear wall systems (rigid or flexible diaphragms)
  • Beams on elastic foundations (multiple spans & shapes)
  • Circular tank (fluid-filled, above-ground or buried)
  • Continuous beams (multiple spans & shapes, hinges and cantilevers)

Built on a simplified, consistent format: Simply enter the geometry, boundary conditions, and loading. No need to construct complex finite element models--the software does it for you. You just describe the conditions as you see a simple sketch of your project unfold. Create individual service load cases and factored combinations easily. Get professional, graphical reports with complete results in just a few pages.

What's Missing?

AnalysisGroup is a workhorse "analysis" tool, it does not perform design checks per building code requirements, nor does it perform detailing. This tool is great (fast, easy, polished) for problems that "fit" within it's boundaries, but it will not analyze "anything" (unlike VisualAnalysis, which is more general-purpose!) IES Customers find the simplicity and speed of AnalysisGroup refreshing on many day-to-day projects, especially the mat footing analysis, and the plate analysis.

New! Version 3.0, was introduced in January 2006 offering a number of important new features.

Six Structural Components

Rectangular Mat Footing Analysis

AnalysisGroup will analyze a rectangular slab on grade with wall loads, column loads, or pressure over an area. Internally the software builds a finite element mesh and iterates the analysis to ensure compression-only support.

Features:

  • Any rectangular mat
  • Column, wall & pressure loads
  • Iterative analysis
  • Extreme result summary
  • Stress contour reporting

Rectangular Plate Analysis

There are many times when you need to look at bending in a flat rectangular plate. Concrete floor slabs or retaining walls are two common examples. AnalysisGroup leverages the power of finite element analysis to solve these types of problems quickly.

Features:

  • You control the mesh size
  • Holes are allowed anywhere in the mesh
  • Any support conditions are permissible:
    • Pinned, Fixed, or Free Edges
    • Rotational Spring Edges
    • Interior Point Supports
  • Any loading conditions, including self-weight

Shear Wall System Analysis

AnalysisGroup will perform flexible diaphragm analysis to determine how a shear force is distributed within a wall, and around openings. Rigid diaphragm analysis is also supported to calculate how a story force is distributed to arbitrarily oriented shear walls in a floor plan. It uses a traditional rigidity solution method for quickly calculating wall stiffnesses and distributing forces to walls and piers.

You simply enter the wall sizes, locations, and orientations. Add window and door locations to each wall as necessary. Then apply loads and AnalysisGroup does the rest. The analysis is very fast with concise and excellent graphics. Printed reports help you to document your analysis and provide the details you need for design work. You may also export a text-report to virtually any Windows program for further post-processing or design work.

A great tool for the analysis of concrete or masonry shear walls!

Features & Benefits

  • Flexible or rigid diaphragm analysis
  • Multiple load heights on flexible diaphragm (single wall) analysis
  • Unlimited number of walls in rigid diaphragm analysis
  • Unlimited openings
  • Minimum eccentricity support
  • Pier stresses calculated
  • Concise, professional report
  • Incorporate braced frames among the shear walls

Beam on Elastic Foundation Analysis

AnalysisGroup analyzes grade beams. A finite element model is created that includes beam elements and spring supports to represent a soil supporting the beam. An iterative analysis is performed to ensure the springs are compression-only.

Features:

  • Up to 10 spans
  • Automatic soil-spring generation
  • Intermediate supports
  • Point, uniform or linear loads
  • Deflections, shears, moments, and bearing
  • Concise, professional report

Circular Tank Analysis

AnalysisGroup will analyze circular fluid-filled tanks. Using an advanced axisymmetric shell element the software creates a sophisticated model, while you simply enter the height of the wall, thickness, and a radius. Advanced loading capabilities allow you to model above or below ground tanks, handle thermal gradients, and deal with covers or equipment at the top of the wall.

Beautiful color reports show the model and the analysis results concisely with professional detail. You may export a text report to virtually any Windows program (like MS Excel) for post-processing or design work.

Features:

  • Wall and footing with various support conditions
  • Internal fluids, external soil height & surcharge
  • Temperature variation
  • Additional wall loads
  • Calculates hoop forces in wall and footing
  • Simple free-body diagrams in reports
  • Determine steel requirements in concrete tanks

Continuous Beam Analysis

Many times, you don't need a high-powered finite element program. For example, you just have a simple multi-span beam to analyze. AnalysisGroup makes it almost trivial to define the model, supports, hinges, and loads. Incredible reporting makes it very easy to showcase your work to colleagues and clients.

Features:

  • Up to 10 continuous spans, with supports, hinges, or cantilevered ends
  • Database of steel, wood, and cold-formed shapes
  • Analyze any arbitrary cross section with specified inertia.
  • Rotational and spring supports
  • Uniform, linear, or point loads, and automatic self-weight
  • Colorful deflections, shears, and moments graphically displayed

What's the "Big Idea" with AnalysisGroup?

Avoiding finite element modeling! The software does it for you. With well-defined project types, the software can do more work for you in terms of setting up the models and also in creating beautifully formatted reports! See for example, these sample report PDF files:

Shapes and Materials

AnalysisGroup makes use of the IES Shape Database for continuous beams and grade-beam projects. You can use ShapeBuilder to create custom member shapes or import libraries of foreign shapes. All the projects make use of the IES Material Database, which is also customizable through ShapeBuilder.
