Ultimate stress increment is a hotspot problem in theory of unbonded partially prestressed concrete structure , however , according to design critera and the art of the state on this issue around the world , it is still not considered in reason that ultimate stress of unbonded tendons in prestressed concrete multi - span continuous structures varies with load cases 無粘結筋的極限應力增量一直是無粘結預應力混凝土結構理論中熱點問題,而從目前各國的設計依據及研究現狀來看,還沒有合理考慮多跨連續結構的無粘結筋極限應力隨荷載工況變化的情況。 |
