摘要
分析预应力钢筋混凝土正截面承载能力极限状态计算公式。对预应力钢筋强度设计值与其有效预应力之间这一强度差值的设定值,可以由计算张拉控制应力来确定。文中给出公式,提供算例,做出结论。
That have analyzed prestressed reinforced concrete normal section calculate formula of beating capacity limit states.As to strength design value of prestressed tendon and value of effective prestress （fpy - Ope） this strength difference of value design, this is built up by tensioned control stress. The paper provides calculate instance, formula, and conclusion.
