一、部分预应力混凝土的概念随着预应力混凝土的发展,按照施加预应力程度的不同分为全预应力混凝土和部分预应力混凝土。所谓全预应力混凝土,有人亦称为充分预应力混凝土、正常预应力混凝土等。全预应力混凝土施加预应力的目的,是为了使结构在标准荷载作用下,混凝土受拉区边缘纤维保持压应力或零应力; First, the concept of partial prestressed concrete With the development of prestressed concrete, according to the degree of prestress applied to the prestressed concrete and partially prestressed concrete. The so-called full prestressed concrete, also known as fully prestressed concrete, normal prestressed concrete. The purpose of prestressing the fully prestressed concrete is to maintain the compressive stress or zero stress of the fiber in the tension zone of the concrete under standard load.
