In this paper a calculating method for predict-ing the ultimate compression strain of CFT is presented for the first time,which is based on an energy balance approach. 钢管混凝土极限压应变是钢管混凝土结构抗震设计的重要参数之一。
The creep strain is then treated as the compulsive strain and the finite element method for creep analysis of the segmental construction concrete bridges is derived. 并视徐变应变为强迫应变，推导了节段施工桥梁徐变分析的有限元方法。
Along with the lowering of the load capacity of the derrick, the strain parameters of the structure change accordingly. 与承载能力降低的同时，井架结构的应变参数也发生相应的变化。
