Slab to Column Moment Transfer Load Path
Slab to Column Moment Transfer Load Path
(OP)
For two-way flat plate construction, thread thread726-155029 discussed the amount of unbalanced moment that is transferred by flexure from the slab to the column. That is clear. What is unclear, however, is the exact load path by which the moment transferred by flexure from slab to column takes. For an interior column, for example, the slab flexural bars are located at the top of the slab and are continuous through the joint. How does the tensile moment developed in these bars get resisted by the column? I am unclear by the load path. Please clarify.
Thanks
Thanks

Similar to the truss method for shear in a beam.

It must be the concrete which transfers the moment from slab to column because, as you say, there are often no continuous bars from slab to column.
Think of a wrench on a nut, all the torque is transferred by compression.
(Edge columns and top floor slabs do require lapped slab and column bars.)
