摘要
本文基于Ｂｏｃｋｉｎｇｈａｍπ定理，推导了考虑建筑物活载和非结构构件质量效应的地震模拟实验的相似关系。另外，针对振动台承载能力有限等实际问题，建立了地震模拟实验的一致相似律，可以得出介于人工质量模型和忽略重力模型之间的相似关系。人工质量模型和忽略重力模型仅是模型设计中应用一致相似律的两种特例。
ln order to improve the restults of shaking table tests a scaling law for live loads and mass of non --structural components of buildings was provided by Bockingham πtheo- rem. After that a general sitanilitude law was developed in consideration of the limited load --bearing capacity of shaking tables. lt is useful for the design of building models without enough artificial mass. The artiticial mass law and the gravity forces-neglecting law are only two special cases of the general similitude law.
