Abstract: In this paper，the non-nodal connection method and the steel-arm method are introduced．According to the comparison the two methods，there is a result that the non-nodal conection method is a more widespread method of limited dements．Through the comparison of the numeric computation with the non-nodal conection method and the numeric results with the analytic results，the correctness and accuracy of the technique is verified and its convenience is demonstrated．

Key words: limited dements, non-nodal conection, steel-arm method
