What are reinforced plates?  此篇文章提出，使用 BEM 方法分析有加強材之平板的彎曲。

BEM formulation  將有加強材之平板 BEM 公式化，是根據於局部施加一初始力矩並推導出其勁度，因為加強材的存在，所以只需在加強材與板材的接口處做區域積分。

Why?  因整體系統勁度的增加，每個係數可以被考慮為獨立的，因此可以方便地減少自由度數量的需求考慮。  當考慮樑的彎曲勁度時，只需看內部每節點的單自由度。文章內有提出例子證實 BEM 公式化的準確性。

Conclusions  考慮自由度多寡的主要原因是受到樑寬的影響。  即使加強板簡化到只考慮樑的勁度，還是能維持整體結構元素的特性。  同樣的問題，自由度減少簡化到只考慮樑勁度的方法與其他方法比對 ( 邊界元 / 有限元耦合，分區域的技術等 ) ，經過幾個例子的測試，發現這簡化的求解方法很精確，特別是在求解內力問題
