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. 鋼管混凝土極限壓應變是鋼管混凝土結構抗震設計的重要參數之一。
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. 並視徐變應變為強迫應變，推導了節段施工橋樑徐變分析的有限元方法。
Along with the lowering of the load capacity of the derrick, the strain parameters of the structure change accordingly. 與承載能力降低的同時，井架結構的應變參數也發生相應的變化。
