Shear centre:
The shear centre is the point through which if the resultant shear force acts then the member is subjected to simple bending without twisting.
Location of shear centre:
(i) Shear centre generally does not coincide with the centroid of section except in special cases when the area is symmetrical bout both axis.
(ii) Shear centre always lies on the axis of symmetry if exists.
(iii) If there are two or more two axis of symmetry exist, then the shear center will coincide with the point of intersection of the axis of symmetry. In this case shear centre of the area will be the same as the centroid of the area.
(iv) If a section is made of two narrow rectangles then the shear center lies on the junction of both rectangles.
