超静定的 meaning in English

hyperstatical
redundant
statically indeterminate

The truss arch structure is a three - dimensional higher statically indeterminate structure , and no definite expression of the performance function can be given for its unbelievable complexity
桁架拱结构是一个高次超静定的复杂三维结构，构件的功能函数没有明确表达式。
But because of an indeterminate flexible structure with many degree of redundancy , its variant inner force under dead - loading , nonlinear behavior and the correlation between construction method and completed structure , especially incessant conversion of system in construction method , these must bring many complicated change to construction internal force and displacement . these main factors resulting in construction control analysis become more important in the design of cable - stayed bridge
但由于它属于高次超静定的柔性结构，恒载内力状态具有多样性、结构状态呈非线性、施工过程与成桥状态具有相关性，特别是在施工阶段结构体系的不断转换，必然给桥梁结构带来较复杂的内力和位移变化，这些特点使得斜拉桥的施工控制分析成为突出的研究课题。
