TANGENGT STIFFNESS MATRIX OF MEMBERS OF LATTICED SHELL CONSIDERING JOINT'S STIFFNESS

In this paper, a tangent stiffness matrix of members of latticed shell was derived on the basis of using Timoshenko's beam-column theory. In this matrix, not only coupling effects of bending in two axes but also joint stickness and joint size were considered. Higher order terms in the displacement function were considered, so this matrix was more precise than Oran's tangent stiffness matrix. An exaxnple of a single layer reticulated shell was provided, which verified the correctness of the present model.
