An algorithm is presented for the evaluation of the linear stiffness matrices on the CDC CYBER 205 computer. Discussion is focused on the organization of the computation and the mode of storage of the different arrays to take advantage of CYBER 205 pipeline (streaming) capability. The algorithm is based on partitioning the element stiffness matrix by rows and columns into nodal submatrices and generating simultaneously the coefficients in all the nodal partitions for a group of distinct elements. An assessment is made of the performance of the proposed algorithm for generating the stiffness matrices of shear-flexible shallow shell elements having 5 degrees of freedom per node. The nomenclature used is given in Appendix II.
