Web12. feb 2024 · In working through the design of a (3) dimensional truss with an inverted triangular cross section and a span of nearly 100ft, what would the unbraced length of the (2) top chord compression members be? Is it accurate to consider the unbraced member length the distance between the diagonals, in both the Lz and Ly directions? Web[ top] General geometry For efficient structural performance, the ratio of span to truss depth should be chosen in the range 10 to 15. The architectural design of the building determines its external geometry and governs the slope (s) given to the top chord of the truss.
