Steel Beams With Web Openings Calculation Spreadsheet
This spreadsheet determines whether a steel beam with known loads, and hence known Moments and Shears, can have web openings added. The first worsheet will determine if an opening can be added at a specific location without reinforcement. The second worksheet goes through the same check as the first and then determines what reinforcing is necessary. The third spreadsheet is the steel data tables as made available by AISC.
