Loads: a takeoff and a load combination table.

Start

The Loads tab of the wizard has wind, snow, seismic and more. These types give the loads you enter in other calculations, so they do not pass or fail. Their status reads Calculated.

The inputs

Here is a load takeoff for a floor beam: a 30 foot span, a 10 foot tributary width, 65 pounds per square foot dead, 50 live, with live load reduction on, for an interior beam.

The results

The line loads are 0.650 kips per foot dead, and 0.431 live. The end reactions are 9.8 and 6.5 kips. These are service values with a load type, exactly what the beams ask for.

The check

The tributary area is 300 square feet, so the live load reduces from 50 to 43.1 pounds per square foot. The check row confirms it stays above the limit of 25, from ASCE 7.

Combining effects

The Load combinations tool combines effects by load type. Here, with dead, live and wind, the largest axial load is 216, under 1.2 dead plus 1.6 live. The largest moment is 163, under 1.2 dead, wind and live. Every combination is listed, so use it to check another program, or to size something this app does not design.

Report and sheet

Then print the report, with every check, its equations and its clauses. Print the drawing sheet on your own title block, at the size you choose. Or export the same sheet as a DXF for your CAD software.
