Doubly symmetric shapes

Websymmetric shapes, the shear center is on the line of symmetry. For doubly symmetric shapes, such as W-shapes, the shear center is at the centroid. For channels, see Figure 3.1 and the associated equa-tions for e 0. For angles and tees, the shear center is at the intersec-tion of the midlines of the elements of the cross-section.
