Thanks to some mental prodding from Roy Diffrient, where he reminded me to
look at Jim Miller's design http://www.jtmiller.com/ I have added some
new analysis of a 'compact' triangular truss to my website at:
http://overton.tamu.edu/aset/krajci/truss-analysis/truss-analysis.htm
I also retain the analysis of the original/wide (31 inch wide) triangular
trusses to compare against the compact (17 inch wide) triangular truss.
I find that a compact triangular truss is about 25% less stiff than the
typical 8 member ATM truss.
I may have fixed one error/omission...but there may be others! ;-) All
feedback is welcome.
Thanks in advance,
