橋梁的設計和計算，獲得符合實際的受力性能，一直是擺在
橋梁工作者面前的一項迫切任務。
Arcuated built - up system bridges are one of bridge structural styles, which are used extensively at present. on one hand, because of complexity and diversity of this kind of structure, current engineering experiences have not satisfied design requirements no longer. on the other hand, towards this kind of structural system traditional methods simplify complicated structures into planar structures, these methods neglect apparently spatial action among members, especially those primary bearing load members along lateral direction of bridges
拱式組合
體系
橋梁是目前廣泛採用的一種
橋梁結構形式，一方面由於拱式組合
體系
橋梁結構的復雜性和多樣性，現有的工程經驗已不能滿足設計需求；另一方面對于這種結構
體系過去的傳統做法是將復雜結構簡化成平面結構，這種做法顯然忽略了構件之間的空間作用，尤其是沿
橋橫向存在主要承力構件。
