Shear centre is an important geometric property of thin-walled sections that can be difficult to determine in practice. A computer based solution is developed for sections comprising an arbitrary number of limbs attached to each other at end nodes. Linear equations are identified that are sufficient to determine the shear flow in each limb and the shear centre is derived directly from their solution in a compact, closed form. The method is applied to sections with straight uniform limbs, and a specific example is evaluated.
