Stiffness matrix for truss element
Web2.7 Total Global Stiffness Matrix of Plane Truss Element. The global vectors of end-actions (Eq. 2.3.4), end-translations (Eq. 2.4.4) of a plane truss element were presented in Sections 2.3 and 2.4. The components of these matrices are not independent to each other, since the existence of global end-actions give rise to global end-translations ...
