Abstract:

The influence of stitch design and local buckling on the seismic behavior of welded bracing members made of double angles is studied in this paper. Performance of boxed configuration with closely spaced stitch welds and continuous stitch plate is shown to be much superior than that of the back-to-back angles with stitches designed in accordance with the current practice.
