3D Frame with zero stiffness hinges
The previous version of 3DFrame allowed for spring releases at beam ends, but if the release stiffness was entered as zero it was treated as a rigid connection for that freedom. Effectively zero stiffness releases could be modelled by entering … Continue reading
Installing Frame4 and 3DFrame
Following a recent comment I have added a VBA only version to the download files of the frame analysis spreadsheets: 3DFrame.zip Frame4.zip The VBA versions should work on any version of Excel from 2007, with macros enabled, without any further installation. The … Continue reading

3DFrame update
The update to the Glob_to_loc3 and Loc_to_glob3 functions (and associated functions) has now been transferred to the 3DFrame spreadsheet, which will now give correct results when beams are defined in the global negative Z direction. The revised spreadsheet (including full … Continue reading

3D Frame analyses with spring releases – 2
The latest version of the 3DFrame spreadsheet (previously presented here) includes provision for spring end releases, allowing for either rotational or translational springs in any direction. These springs are now incorporated in the model by adjustment of the beam properties, … Continue reading

3D Frames, axes and stiffness matrices
In the course of adding provision for spring end releases to the 3DFrame spreadsheet, I have also tidied up the code for generating the structure stiffness matrix, and added some documentation to the spreadsheet. The revised spreadsheet (version 2.02) can … Continue reading

Run Fortran from Excel with Python and F2Py
I have previously posted on the use of the Silverfrost Fortran compiler with Excel (e.g. Linking Excel to Fortran). More recently I have been concentrating on accessing high performance compiled routines via Python and the Python maths and science libraries … Continue reading
