A composite coupling beam frames at the top of a reinforced concrete wall with web plates omitted for clarity. The coupling beam top flange extends per standard composite coupling beam details and features a cap plate welded at the ends. Specific fillet or groove welds designated as Wf are applied within the coupling beam span and top flange extent per referenced typical details. Outside the flange extent, welding conforms to standard top of wall connection details. Openings within the assembly are restricted unless specifically detailed, with dimensions verified from the elevations.
