Key Features

  •  STAAD.foundation can automatically absorb the geometry, loads, and results from a STAAD.Pro new model to design foundations. It even keeps track of changes made in the STAAD.Pro model and can merge reaction output to the existing foundation model.
  • STAAD.foundation produces production-quality reports and detailed 3D renderings of your foundation structures. With full OpenGL graphics, engineers can clearly see the displaced shape, stress distribution, reinforcement layout, and force diagrams of their supporting structure.
  • Version 5.0 produces production quality detailed drawing along with GA drawing and footing schedule drawing.
  • All models use physical objects including physical beams and slabs that do not require meshing. "General Arrangement" (GA) drawing is a valuable tool as it shows the actual footing positions and sizes and even checks for overlaps. Calculation sheet is another popular tool, showing detailed step-by-step calculation with relevant code clauses and equations.
  • For mat design, STAAD.foundation uses a true finite element design using the individual element stresses rather than using column strips. It can automatically detect slab areas out of contact with the soil and redistribute forces to other parts of the slab. You can design along any line on the slab and check for punching shear for all column positions.
  • STAAD.foundation supports three international design codes:

    • ACI-2005
    • BS 8110
    • IS-456 2000
    • AS 3600-2004
    • CS A23.3-04
  • To address specific needs of plant industry, program includes modules like vertical vessel foundations (both octagonal and square shape) and heat exchanger foundations. Both types of foundations can be supported on soil or on piles with automatic wind load generation and zip code-based seismic load calculation.
  • Foundation toolkit mode is introduced to address the needs of special footing types like "Drilled Pier" and "Dead man anchor guy" foundation. Both modules can take multiple layers of both cohesive and cohesionless soil.
  • Includes a myriad of foundation configurations such as spread (isolated) footings, strip (combined) footing, pile cap, mat foundations, plant foundations such as vertical vessel and heat exchanger foundation and specialized footing types such as drilled pier and dead man anchor guy foundation.
  • Mat foundation design includes both slab-on-grade and slab-on-piles. It helps you visualize and optimize footing design with different integrated footing design modules.
  • Automatically detect slab areas out of contact with the soil and redistribute forces to other parts of the slab. The entities and the graphical representation of the mat foundation output such as displacements, forces, and stresses are shown using OpenGL for a realistic rendered view.
  • Incorporates Rigid and Flexible Methods of Design - STAAD.foundation includes both rigid and flexible methods of foundation design. Spread footings, combined, strip, and single column pile caps are designed using rigid methods to match the steps of a design engineer. It also has fully capable FEM analysis where the user can model a simple footing or large mat. It provides a sophisticated and accurate tool to analyze and design mat foundations for multiple regions with different soil properties, thickness, holes, and beams.
  • Provides Auto-Meshing and Physical Loading for Mat Foundations - We understand the frustration and time you might face in converting a physical mat into thousands of analytical components in order to do a sophisticated FEM analysis. STAAD.foundation eliminates this step by creating analytical components with auto-meshing. However, the output and design results are based on physical entities like slabs and beams. You can automatically convert local axis analysis results to a global (or user defined) axis system. This not only saves time, it reduces errors significantly.
  • FEM Analysis for Accurate and Economical Designs - STAAD.foundation has a very unique and innovative technique for mat design that takes full advantage of FEM analysis, which can provide for an accurate and economical design. It designs the slab at thousands of discrete points taking into considerations unlimited number of load cases. This unique approach to creating user-defined reinforcing zones helps the user to visualize and optimize the reinforcement requirement. You can even select a section on any part of the mat and design reinforcement along that cut line. Punching shear checks are also included at columns.
  • Easily Handles Complex Foundations - STAAD.foundation handles rectangular, complex polygonal, circular and elliptical shapes. In addition, you can model both regular and irregular column lines. The sophisticated mesh generation algorithm allows you to create holes (cut-outs) and inner regions with different thicknesses to simulate pedestals. Loads automatically transfer from the top of the pedestal to the base of the foundation. The user can specify unlimited number of load cases for analysis and design.
  • Thorough Output Including Calculations - Since STAAD.foundation is developed by engineers, it understands an engineer's need to review results by presenting a detailed calculation sheet. STAAD.foundation lists all relevant code clauses with equations and calculated values. You can follow the method used in the program and feel confident with the results. Our calculation sheet is based on XML format so your clients can view the calculation with any Web browser even if they don't have the software.
  • Detailed Drawings Directly from the Program - Detailed foundation drawings are exported via DXF format to create site drawings, including both plan and section drawings with rebar marks in both longitudinal and transverse directions. Layout drawings are also provided and include all the footings designed in the project to scale with grid lines and grid marks. With the help of this drawing, users can check for mistakes-and the program actually marks all overlapped regions.
  • Automatic Pile Arrangement - STAAD.foundation includes a wide range of predefined pile arrangements to save you time. In addition, the program can automatically select the best possible pile arrangement for a given pile capacity. The BOCA standard is followed for predefined pile arrangements.

Files and Interoperability

All STAAD.foundation modules are integrated and share the same loading data.  

STAAD.foundation is completely Integrated Design with STAAD.Pro (Bentley's leading product in structural analysis and design) with bi-directional flow. You can open any STAAD.Pro file and import all column positions, support reactions, and so on. It even keeps track of changes in the STAAD.Pro model. If the superstructure gets updated, you can easily merge new output results within STAAD.foundation file.
STAAD.founation uses .AFS files for saving data.

Product History

The first version of STAAD.foundation was released in September of  2004.

To address specific needs of the plant industry, version 4.0 included modules like vertical vessel foundations (octagonal shape) and heat exchanger foundations. Both types of foundations can be supported on soil or on piles.
