RE: Intermediate Stiffener<Spacing and Numbers>
Otherwise, just use 4 and you're good.
Oh, you may want to consider the girder span, girder spacing, loading, web thickness, web depth, Fy, Fu, E, fb, V, M, flange plate dimensions, diaphragm spacing, point of contraflexure (only if continuous of course!), composite/noncomposite, tension field action, LTB restrictions ..........
RE: Intermediate Stiffener<Spacing and Numbers>
FYI: Stringer schedule provides spacing of intermediate stiffener.
Also, should i add total number of stiffener from stringer schedule should to diaphragm connection plate too or it should be excluded from total number of stiffeners?
RE: Intermediate Stiffener<Spacing and Numbers>
The old rule of thumb before steel prices went through the roof was that a designer would use a web thickness that precluded the use of stiffeners minus an 1/8". As a result, not many stiffeners were used on bridges, especially those with wide flange stringers. Stiffeners are more common on plate girder bridges.
