i saw a thread on calculating the torsional constant, j listed in table 1-25, page 1-89 of the aisc manual for shapes not listed in the manual. although, it seemed like only how to evaluate torsion was explained. does anyone know how to calculate this value. i need it only for equations f1-8 and f1-9 in the manual.
the torsion constant is a geometrical property of a bar's cross-section which is involved in the relationship between angle of twist and applied torque along the axis of the bar, for a homogeneous linear-elastic bar. the torsion constant, together with material properties and length, describes a bar's torsional stiffness.
deformations are small, and the warping torsional constant is generally taken as zero. shear centre the shear centre, or torsion centre, is the point in the plane of the cross section about which twisting takes place. the shear centre location is required for calculating the warping torsional constant and the monosymmetry constant.

the paper deals with the torsional behaviour of bridge composite girders, built with plated i beam and top concrete slab. this typology has different variants in the way transverse bracing diaphragms are designed, either strut-and-tie type or flexural, and in the optional presence of a bottom horizontal torsional bracing.
beams subjected to torsion and bending-ii beams subjected to torsion and bending - ii 18 1.0 introduction in the previous chapter, the basic theory governing the behaviour of beams subjected to torsion was discussed. a member subjected to torsional moments would twist about a longitudinal axis through the shear centre of the cross section.
bending and torsion, both in terms of resistance of the cross section and in terms of resistance against lateral torsional buckling. torsional parameters for a range of rolled sections are given in an appendix. six short worked examples illustrate the verification for typical design situations. summary
torsional moment of inertia, it. the torsional moment of inertia, it, is taken to be a simple sum of torsional stiffness values for the individual cross-section parts. warping constant, iw. the warping constant, iw, is taken as the sum of warping constants of the individual cross-section parts.
in review of aisc dg9 it appears j for an open section can be calculated as the sum of bt^3/3 which would make me believe the torsional constant would be additive and the composite 'j' is not dependent on the spatial relationship of the members in the composite shape?
shapedesigner composite section properties calculator software, torsion and warping constant shapedesigner saas is an advanced general beam section calculator. shapedesigner calculates the cross-sectional torsion and flexural structural properties , including torsion constant j , warping constant cw , normal, warping and shear stresses.
real torsion and warping constants contrary to most software available, shapedesigner makes no assumptions or restrictions on the calculation of shear and torsion section properties. shapedesigner uses an advanced and efficient finite element approach to calculate these constants.
what is the torsion constant? december 5, 2013 by bernie roseke, p.eng., pmp 6 comments in structural steel design, the torsion constant, j, represents the ability of the steel beam to resist torsion, i.e. twisting.
the torsional constant is a physical property of a material. it is most commonly used to describe metal beams and is denoted by the variable 'j.' when a torque is applied to a metal beam, it will twist a certain angle. the angle that the beam twists depends on the beam's rigidity, length and torsional
calculating torsional constant sorry if this counts as asking for homework help i'm designing a chassis for a project. i need to look at how it behaves with a torsional load. i'm assuming it's two unconnected constant x-section beams to make the maths vaguely doable. how do i go about calculating the torsional constant?
