在出現問題前材料單位面積所能承受的極限拉力，例如：磅每平方英寸( psi ) 。

An important step in structure design is the calculation of the ultimate flexural strength of external prestressed concrete beams , which needs to calculate the ultimate stress increment of external tendons first
結構設計的一個重要環節就是極限承載力計算,而計算體外預應力混凝土梁的極限承載力就必須求得梁在破壞時的體外筋應力增量。

At last , the effect of the steel yield strenth , the yield - to - ultimate stress ratio , the shape and size of the access hole is researched . in conclusion , the finite - elenent model and the program adoped in this paper can well similate the response of beam - to - cloumn connections uder cycpc load
