For many decades the designs of earthquake-resistant (aseismic) structures have been influenced by scaled experiments, underpinned by the theory of dimensional analysis. Although scaled experiments still play an important role, they are recognised to suffer shortcomings, which are particularly severe when scaling ratios are pronounced. The issue is one of scale effects and the inability of dimensional analysis to offer any solution in their presence.

This paper is concerned with a new theory for the analysis of aseismic structures that is founded on the metaphysical concept of space scaling, where beams, substructures or buildings etc. are contracted through the mechanism of space contraction. Although space contraction is evidently practically impossible the theory describes the effects of such a process on the underpinning governing mechanics involved. Unlike dimensional analysis the approach which is termed finite similitude embraces scale effects and accounts for them by linking experiments at more than one scale.

It is demonstrated in this work how it is possible to reconstruct full-scale behaviour by means of two scaled experiments of a selected beam, column and multi-storey structure when subjected to dynamic loading conditions.

数十年来，抗震（抗震）结构的设计一直受到规模试验的影响，而规模试验则受到尺寸分析理论的支持。尽管按比例缩放的实验仍然起着重要的作用，但是人们认识到它们存在缺点，当按比例缩放比例明显时，这种缺点尤为严重。问题是规模效应和尺寸分析无法在其存在时提供任何解决方案之一。

本文涉及一种基于空间尺度化的形而上学概念的抗震结构分析新理论，其中梁，子结构或建筑物等通过空间收缩机制收缩。尽管空间收缩显然实际上是不可能的，但该理论描述了这种过程对所涉及的基本控制机制的影响。与尺寸分析不同，这种称为有限相似性的方法包含了比例效应，并通过在多个比例上链接实验来解决这些问题。

在这项工作中证明了在动态载荷条件下，如何通过对选定的梁，柱和多层结构进行两次缩放实验来重建满量程行为。
