What is the shear flow for transformed steel?

For bending strength and stiffness, the steel and concrete slab cross section is converted to an equivalent transformed steel section. The shear flow, , required for determining the number of studs is determined from the classic shear equation, Ic VQ =(1.1) Reference: ctr.utexas.edu/wp-content/uploads/pubs/0_4811_1.pdfSee all results for this questionWhat is fastener fatigue?Fastener fatigue Fatigue is the most common form of frac- ture of metal structures, accounting for up to 80% of all costs associated with fracture. Fas- teners are no exception, as fatigue remains the most common cause of fastener breaks.See all results for this questionWhat is bending strength and stud design?Prior to 1960, both bending strength and stud design for composite beams were based on elastic theory.
