Hello, I have a 73.5' simple span, rolled beam LARS V6.00.01.08 analysis that has varying LLDFs due to varying overhang widths at the supports. Using LRFD, I have input three ranges for both moment and shear. When looking at the output tables and…

I am modeling simple-span steel beams with a non-composite concrete deck. What formulas should I be using to calculate the LRFD distribution factors? I note that when I let LARS calculate the factors, the factors calculated when I model it as CSC are…
