ITSdesign Additions

We have just released an update to our ITSdesign API-650 and AWWA D-100 tank design software. In this release we have added the ability to specify a maximum allowable stress for shell plates that is less than what is specified by the code. We also added a link to the USGS website for obtaining the seismic values needed. The biggest addition is that we added the ability to use channels and wide flanges as center and intermediate columns. The column can be either a single beam or it can be a composite beam. Drop down menus allow you to select which beam sections you want to use. Corrosion allowances can also be applied to the beam sections. In addition we have corrected a couple of printing errors. We are constantly working to add to and make corrections to our software.
