We've been hard at work developing a web app that can aid in analyzing and designing shallow foundations in accordance with the Load and Resistance Factor (LRFD) design methodology.
As you can see in the above picture, the first phase of the web app is nearly complete. The first phase of the app will calculate the nominal and factored bearing resistance of continuous or rectangular footings subjected to point loads. Future phases will allow for eccentrically loaded footings and settlement calculations based on Schmertmann's method.
What is pending are tweaks to the user interface, heavy testing to make sure that the calculations are correct, and code clean-up. The next time you hear from us we'll have something for you to calculate around with!
