What kind of simplified structural system would a Leonardo bridge use?
I've tried approximating the system to a simple statically determined beam (see below) but our calculations did not give any realistic results. I believe it is due to a negligence of the potential strain in each beam. Maybe using a Spring Load Constant combined with nodes would help? A Leonardo bridge is a bridge constructed without any kind of binding, but just using uniform length pieces of Wood. It can be constructed in this manner:
My own approximation is rough but each of the connections cannot be considered nodes because none of the pieces are loose or movable.
P.S. It would greatly simplify my calculations if any answers would consider a statically determined system even if it is a simplification.
