Torque-Loaded Continuous Beams of Profile Section
If a beam of thin profile section is continuous over several supports and subjected to transverse loads that do not occur on the shear-center axis, it will undergo torsion as well as bending. Beginning with the general theory of nonuniform torsion for such bars, expressions for the angle of twist, φ along the bar are written for two consecutive spans. From these expressions, a single recurrence-type of formula is derived which involves, as unknowns, only the three quantities of φ“n, φ“n+1, φ“n+2, at three consecutive supports. This recurrence formula is somewhat analogous to the three-moment equation and greatly simplifies the analysis of the torsional behavior of a continuous beam subjected to eccentrically applied transverse loads. Its application to the case of a two-span beam is shown by an example and an experimental study of this two-span case is described. The results of this experiment are in very good agreement with the theory.
