I understand but, what about this theory that says that the top chord is like a beam with intermediate elastic springs, due to the diagonals and the so called U-frame
This is the main truss, the bridge is skewed and floor beam are independet of the main trusses, my question is about the unbraced length, other engineer tell to me that i have to use the total lenght of the top chord for calculatin factores compression strenght
Hi, im designing a pony truss highway bridge with a total span of 85m, the truss is warren type and top chord have an arch form with 7m rise. i have done a 3D finite element model and the buckling factor (obtained with eigenvalues) is more than 1, then i think this is ok, but when im designing...
