Develop the stiffness matrix for a fictitious pure shear panel element (Figure P4-46) in terms of the shear modulus, G, the shear web area, Aw, and the length, L. Notice that Y and v are the shear force and transverse displacement at each node, respectively.
Given
1) ( = G(,
2) Y = (Aw,
3) Y1 + Y2 = 0,
4) ( = v2 - v1 / L
