About this detail

A composite coupling beam assembly features embedded steel web plates and slotted flange plates top and bottom per schedule. Cross ties are spaced at twelve inches along the span, while infill concrete fills the core between boundary elements. A nine by nine inch closure plate matches the flange thickness, and holes are centered at midspan as necessary for adequate concrete consolidation. Complete joint penetration welds connect the plates, and flange plates are widened as necessary to weld to the web plates.
