An A36 W14X605 simply supported steel beam with span L=12.6m carries a concentrated service liveload “PLL” at midspan. The beam is laterally supported all throughout its span. Consider its beam selfweight to be its service deadload, “w” (use ASEP steel manual for selfweight, w and other section properties). Calculate the maximum service PLL that the beam can carry based on flexure requirement using LRFD? Express your answer in KN in 2 decimal places.
