Re: New releases of Multi-Lat Flexible Analysis

[Subject Prev][Subject Next][Thread Prev][Thread Next]
How do you suggest one argue that the use of the flexible analysis is valid when in almost every case it is not possible to show that the walls are not more flexible than the diaphragm and therefore the rigid diaphragm analysis is required by Code?
I know this has been discussed previously but I don't believe we have ever come up with an acceptable answer.

You can now download the latest versions of Multi-Lat™ flexible diaphragm spreadsheet directly from the Structuralist.Net website. There is a dedicated Multi-Lat™ page that contains the flexible analysis and a separate but original rigid analysis that Dave Merrick worked on. I have also started a Blog that will be set up like written documentation including creative uses of the spreadsheet.

If you are using any version of Multi-Lat™ flexible analysis dated earlier than November 03, 2004 then please download the latest version. Many issues for multi-story shear distribution have been fixed. This Excel spreadsheet conforms only to the 1997 UBC or similar California Building Code. It does not cover ICC codes.
