缩尺模型被广泛用于大型土木工程结构的试验研究，这是由于试验实验室设备的局限性，以及缩尺模型的试验装置和制作成本较低。比例建模减小了结构模型的大小，而不会丢失原型行为中的重要特征。缩尺模型应满足相似要求，才能用于足尺(原型)结构的反应研究。然而，关于原型结构与模型缩比的相似规律的研究却很少。在这项研究中，试图建立基于量纲分析的相似关系动态结构模型，量纲分析是一种推导描述物理现象的变量之间理论关系的数学技术。
Reduced scale models are widely used for experimental investigations of large civil engineering structures due to limitations of the facilities available in testing laboratories as well as less costing of the experimental set up and fabrication of reduced scale models. Scale modeling reduces the size of a structural model without losing important characteristics in the behavior of the prototype. Scale models should satisfy similitude requirements so that they can be used to study the response of full scale (prototype) structures scale structures. However, very few studies have been carried out on the similitude rules for scaling down of the prototype structures with the models. In this study, an attempt has been made to develop the similitude relations dynamic structural models based on dimensional analysis which is a mathematical technique to deduce the theoretical relation of variables describing a physical phenomenon.
