在此情况下，进口材料的允许应力与GB150 - 1998中的相当材料相同。
In this case allowable stress of imported material shall be those for equivalent material in GB150-1998 as follows.
以上环节中若出现大于允许应力时，就会导致破坏性损伤，甚至折裂、坍塌等严重后果。
If the above link is greater than the allowable stress, it will lead to destructive damage, or even crack, collapse and other serious consequences.
这类桥梁在设计计算过程中均是按照全预应力混凝土结构进行设计的，施工和运营中任何截面混凝土拉应力均不允许超过允许应力值。
Bridges of this kind are designed according to fully prestressed concrete theory, and tensile stress is allowed to exceed allowable stress during construction and service.
