    Wind Load Comparison of Curtain Wall
    Based upon 35 PSF for 30 days period.

    Curtain wall "A" Single span with 11" + or Minus steel mullions is 3'8" wide X 23'-10" high each section with 2 intermediate horizontals.

    Curtain wall "B" is triple span with the same 11" mullion but is 7'-10" Center to center of the vertical mullions X 23'-10" high each section. CW "B" has two horizontal mullions that butt to a second floor slab and third floor slab.

    Question: Can Curtain Wall "B" have the floor slabs cut back to prepare for new Curtain Wall essentially making CW"B" single span for a period of 30 days? The difference between CW "A" and "B" is about half the width center line to center line. Mullions are identical in both curtain walls.
