COM624 is a freeware DOS based program for the analysis of lateral loads on piles produced by the FHWA in the USA. The program and documentation are available for free download, but are well hidden, so I’m posting links to the download sites here:
COM624 Program no longer available; see below
In coming posts I will post an Excel based pile lateral load analysis program, based on the same principles as COM624.
Update 10 Mar 2018:
The COM624 program is no longer available for free download, and the link to a commercial download is no loner active.
The link to the manual is still active.
The LatPilePY spreadsheet available here is still free, and provides most of the functionality of the COM624 program, with much friendlier input and output. Download from the link, and see the Downloads or Downloads by category tabs for more information.
