Shear Centre in an Asymmetrical Section
Shear Centre in an Asymmetrical Section
(OP)
Hello fellow members,
I am working on the analysis of a section subjected to bending, shear and axial, torsion. The section is asymmetric about both the axes. I would like to know is there any method to calculate shear centre by hand calculations similar to the way we calculate moment of inertia? If the section is symmetric about at least one axis, it would not be a tough task. Please suggest me some references/ methodology, I would be grateful. Please find attached typical section.
Thanks in Advance

You can use excel to goal seek for the shear center by setting torsion = 0

For a singly symmetric (about horizontal) shear center: (1) calculate inertia, shear flow, resultant shear flow, sum moments equal to zero, and solve for shear center axis. (2) draw symmetric axis. (3) find the intersection (shear center).
For an asymmetric shear center: (1) calculate inertia, shear flow, resultant shear flow, sum moments equal to zero, and solve for shear axis. (2) Rotate 90 degrees, repeat step (1), and solve for second shear axis (3) find the intersection (shear center).
