MFJ: Multiple Fastener Connections (WIN/UK/free)

Developed for the research project 'double shear timber connections with dowel type fasteners', by Dr.Ir. Andre Jorissen. With the MFJ program the reduction in the load carrying capacity for multiple fastener connections can be simulated for a variable number of fasteners, depending on the geometry and material properties.
Contact Andre Jorissen if you have any questions about this program.


Notes

Some visitors of our site reported connection problems while downloading one of these free demo's and programs. If you experience any problems, please drop us a line and we will send you the program(s) of your choice by mail. Do not forget to mention what program you would like to receive. (support).

All programs are contained in zip files. If you don't have an unzip utility on your system, you can download an 'evaluation version' from WinZip.

Please note that you have to extract all files. Do not doubleclick the executable in the archive list of your unzip utility such as WinZip. That will not work, because only the program itself will be extracted and started without menu files, producing the error "can not find or process menu template". So mark all files (or none as a matter of fact) and press 'Extract'.
