Optimum Designs for One Footing or Your Entire Structure

RISAFoot provides stand-alone and integrated analysis, plus design and drawing of spread footings and pedestals. RISAFoot is the best because it automates every step from analysis to design to drawing and it goes beyond simple issues to handle complex situations, such as biaxial bending, uplift and property boundaries.

Automatically check bearing pressure, sliding, overturning, and uplift. Designs both footing reinforcement (bottom and top) and pedestal steel and exports DXF details. View detailed reports for each footing, including bearing pressure plots and reinforcement sketches. RISAFoot will create DXF plans, sections, and details of your footing for export to your favorite CAD package.

RISAFoot integrates directly with RISA-3D and RISA-2D, allowing you to design all of your footings at once.

RISAFoot In-Depth

RISAFoot is the complete solution for individual spread footings. RISAFoot allows you to define your own load combinations, including bi-axial loads and bearing increase factors. When architectural constraints require a shift, you can directly specify the required eccentricities. Even handle lot lines and utilities by specifying a fixed distance from a column – in both directions.

RISAFoot handles all the standard serviceability checks: bearing pressure, sliding, overturning, and uplift. RISAFoot automatically sizes each footing, and then designs both the footing and pedestal using the latest ACI codes. You get layouts for both top and bottom footing reinforcement, as well as main steel and ties in the pedestal.

Load Application

Apply vertical loads, shears, and moments, in both directions simultaneously. Self weight and overburden are calculated automatically.

Soil Analysis

Calculate exact biaxial soil bearing distributions using advanced computational methods.

Footing Optimization

Determine the optimum footing length, width and thickness to satisfy soil bearing, bending, shear, uplift, and boundary criteria.

Pedestal Design

Create a full pedestal design for axial loads, biaxial bending and shear with specific results for longitudinal bars, development and ties.

Overturning & Sliding Checks

Separate load contributions for overturning and stabilizing forces satisfy the desired safety factor. Sliding checks verify that the applied forces can be resisted by the calculated soil friction force and user-defined passive soil resistance.

Integration

Full integration with RISA-2D, RISA-3D and the RISA Building System brings productivity to a higher level. Manage all project footings in one model, in one file, and within the same environment as your structure.

All loads are automatically applied and all footings are optimized at once. Changes can literally be handled in minutes rather than hours or days, letting you investigate more design options and helping you adjust on fast-track projects. Detailed foundation plans are automatically generated in seconds.

 

RISAFoot v4 Specifications

RISAFoot sets the standard for analysis and design of spread footings and pedestals. All combinations of axial load, uniaxial moment or biaxial moment are handled accurately, bettering the approximate results found in other applications. It’s the perfect choice for optimal designs for your spread footings, eccentric pedestals and bounding property lines.

Multiple Footing Solutions

As with most RISA software, RISAFoot is more useful in different scenarios because it excels as a stand alone application and it fully integrates with RISA-2D, RISA-3D and the RISA Building System to fully manage structural models from the top down to the foundation. No other software provides this much flexibility. Whether you need to solve a single footing or all footings on the project, RISAFoot automates as much as possible.

• Full integration provides fantastic automation and productivity through one common interface.
• Footing loads, criteria and column information are automatically determined from structural models built with RISA-2D, RISA-3D or RISAFloor.
• Multiple footing results are tabulated in powerful spreadsheets with sorting and filtering.
• Detailed foundation plans are automatically generated in seconds.

RISAFoot does not leave you hanging when your footings aren’t typical. Advanced solvers included with RISAFoot accurately provide solutions to biaxial bending, eccentric pedestals, limiting property boundary conditions, overturning and biaxial pedestal design.
