like the AASHTO explained in C5.2.2
Tests indicate that in the elastic range of structural behavior, cracking of concrete seems to have little effect on the global behavior of bridge structures. This effect can, therefore, be safely neglected by modeling the concrete as uncracked for the...
many thanks to all of you!
if my understanding is right, when doing the load analysis for the girders to get the moment and shear, the full composite section shall be used (means stiffness along the girder shall include the concrete, reinforcement in concrete and the steel)!
however, when...
for slab on steel plate girder continuous bridge, when doing the live load analysis, for negative moment zone, the cracked section or uncracked section properties shall be used to analysis the force? AASHTO C6.10.1.5 said:
"Field tests of composite continuous bridges have shown that there is...
