    "MONORAIL" --- MONORAIL BEAM ANALYSIS

    Program Description:

    "MONORAIL" is a spreadsheet program written in MS-Excel for the purpose of analsis of either S-shape or

    !-shape underhung monorail eams anal#ed as simple-spans with or without o$erhangs %cantile$ers&'

    Specificall( the x-axis and -axis ending moments as well as an torsion effects are calculated' )he actual and

    allowale stresses are determined( and the effect of lower flange ending is also addressed two different

    approaches'

    )his program is a wor*oo* consisting of three %+& wor*sheets( descried as follows,
