关键词:
摘要: Previous developments in the direct stiffness method are reviewed. The advantages of extending definitions to make a variational approach cited. finite element formulation minimum potential energy is given. Explicit requirements displacements presented, and criterion insuring monotonic convergence developed. Illustrative yielding matrices resulting included. Available reviewed with respect extended developments.
