Beam & Support Properties

Total Beam Length (L_beam_total, ft):

Support A Location (a_support, ft from left end):

Support B Location (b_support, ft from left end):

Loading & Analysis Properties

Surface Load at Start (w_start, lbf/ft² or psf):

Surface Load at End (w_end, lbf/ft² or psf):

Tributary Width (ft):

Convert Distributed Load to End Point Loads (Calculates reactions of the full distributed load as if simply supported at its ends, then applies these reactions as point loads at the actual beam ends)

Number of Data Points (num_points):
