Based on the analysis and theoretical derivation, the whole process of prestressed concrete cylinder pipe (PCCP) under internal load was investigated.
通过分析与推导，研究预应力钢筒混凝土管(PCCP)承受内水压荷载下的全过程。
The large deflections and stiffness changes usually associated with plastic bending can significantly change the internal load distribution, particularly in statically indeterminate beams.
随着塑性弯曲而发生的挠度和刚度大的变化常会使结构内部发生显著地内力重分布，特别是超静定梁中。
