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
