• Abstract: The support in engineering is closer to the elastic support. It is of practical significance to study the calculation of statically indeterminate structures with such supports. This paper presents the analysis of the statically indeterminate structures with elastic translational support based on the moment distribution method. Firstly, the rotation stiffness and the fixed-end bending moment under common loads for the single-span statically indeterminate beam with elastic translational support are derived. An example of the statically indeterminate rigid frame is given in the end. 工程实际中的支座更接近于弹性支座，研究此类支座下超静定结构的计算具有工程实际意义。文中提出用力矩分配法计算具有抗移弹性支座的超静定结构，首先推导了具有抗移弹性支座的单跨超静定梁的转动刚度以及常见荷载作用下梁的固端弯矩，然后给出了超静定刚架的具体算例。
