    它與常規的下承式拱架支承結構的最大區別在於它的兩道下弦桿設置了四道斷縫，從而使下弦桿失去對拱腳水平力的約束作用。
  4. You stand on large ” the moon ", seeing moon, such as great arched door in the view park of full string, hole crest the clock milk which hang a full and strange form strange form stone, like wreath form mountain

    您站在碩大的"月球"上，看到月亮如滿弦的大觀園拱門，洞頂掛滿奇形怪狀的鐘乳石，有如環形山。
  5. The pre - stressed arch truss string structure is one of the new pre - stress steel structure styles, because it possessed of rational mechanical feature, it has been used in many national and foreign engineering practices

    預應力張弦拱桁架結構是一種新型的預應力鋼結構形式，由於其受力合理的特點在國內外工程實踐中得到了較多應用。
  6. This paper analyses multi - stage pre - stressing and different parameters produce the impacts to static and dynamical behavior of the structure by theoretical calculation and experimental research. the conclusion can provide reference to static and seismic design of arch truss string structure. the main issues in the paper are : the multi - stage pre - stressing loading experiment is studied in this paper
