摘要
针对现行承载力计算公式较为抽象且不易考虑侧限对预应力传递影响这一现实，论述了预应力筋的两阶段工作原理，并基于该原理建立了能较好地反映预应力本质的无侧限及有侧限预应力混凝土结构承载力计算公式。
Since the current bearing capacity calculation formula are abstract and without consideration of the influence of lateral limitation on prestressing transmission.It's firstly discussed the two-stage-work theory, secondly based on this theory,the bearing capacity calculation formula of lateral and non-lateral limitation prestressed concrete structure are established,which grasp the essence of prestressing property.
