| 摘 要： | 本文提出一种二结线超级矩形条元，用来分析板梁组合结构，做法是将板梁组合结构离散为若于个超级余元，在超级元内按常规有限元法离散。采用常规元自由度向超级条无自由度的转换减少未知量，可大大节省计算机存贮空间，提高计算效率，同时还能保证计算精度，并通过算例验证了正确性及其优点。

| Abstract: | This paper presents a two nodelines rectangular super strip element for analyzing built-up structure with plate and beam system, the structure is partitioned into manyrectangular super strip elements. and the further partition is done in the super strip elementby ordinary FEM. The unknowing varies are decreased by transfer the DOF of ordinary elements to the DOF of super strip element, and the accuracy of the proposed method is well.The correctness and the advantages of the method are checkde by the numerical example. |
