Analyzing a design using Safe Load adds 2000 pounds as an additional load, located where maximum stresses occur. BC Framer® and BC Calc® distribute the additional load over a 2.5' x 2.5' area, yielding an additional 320 psf. The analysis moves this load along the span to find maximums for shear and moment. This 'safe load' replaces the live load. The results are saved for the worst case (defined as the highest percentage of allowable, either shear or moment).
Note: When used, the Design Report includes an ―SL*‖ load case and a Note describing the analysis.
