What's New

This update to our footing analysis and design software includes many new features such as ACI 318-05 and is certain to be a valuable tool for your office.

Overview

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.

Why RISAFoot Stands Apart

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.
