Bending stress - multiple loads
Bending stress - multiple loads
(OP)
Hello all,
How do you calculate the maximum bending stress for a beam (multiple span) that has multiple evenly spaced point loads? For example, point loads at 12'' on center along a hat channel.
Would using 3PL/16 be considered worst case moment?
Thanks.

You could always assume its a distributed load.

Look at table 3-22C "Continuous Beams; Moments and Shear Coefficients Equal Spans, Equally Loaded" of the AISC Steel Construction Manual. It has moment distribution for distributed loads as Desertfox mentioned, and point loads up to quarter points of each span
