I'm creating a computer implementation to solve planar trusses. And I'm not sure how to check if the truss is solvable or not. Can you help me with that?(adsbygoogle = window.adsbygoogle || []).push({});

In my implementation, the trusses are created randomly (needs to be this way), so i get a lot of unstable or indeterminate trusses. I want to discard bad trusses without calculating the determinant of the stiffness matrix or trying to solve them.

Is this condition enough to discard such trusses? If I filter the trusses with this criteria, will i lose some good ones? ----> 2j = m+r

j - number of joints

m - number of members

r - number of reactions

Thanks.
