摘要
在预应力混凝土连续梁桥计算机程序设计中,预应力钢束项的描述方法是程序设计中的关键,本文提出用“导线法”控制预应力钢束的数学模型,控制多数少,预应力及二次力的计算符合实际受力状况。
In design of presstressed concrete continuous beam, the description of the prestressing tendon is the key- Its mathemahcal modcl should be less controlling parameter,The calculation of prestress' loss of prestress, and the secondary internal force Should be accord with the actual case.
