摘　　要：拟静力试验是目前结构工程抗震研究领域中最常用也使用最为广泛的试验方法之一。通过该试验技术,可以获得不同试验目的下的试验信息,从而为抗震设计、规范条文的修订完善及结构分析模型的提出发展提供强有力的支持。加载制度是拟静力试验方法技术中的关键核心问题,而在试验中并未引起足够的重视。本文基于加载制度的重要性,从概念上着重论述了不同结构类型的加载制度,阐述了加载制度产生的原则和方法,并指出了当前所采用的加载制度中存在的缺陷问题。Quasi-static test is one of the most common experimental techniques, which is also widely used in the field of structural engineering for seismic research. Through the test technology, information under different experimental purposes can be obtained and supplies as a strong basis for seismic design,revision of standard clauses of seismic codes, as well as development of analytic models for component or structure. Loading protocol is one key issue of quasi-static test nevertheless is often not paid much attention to during the whole experimental program. The importance of such issue is emphasized and different kinds of loading protocols are given then commented. In addition, determination of a loading protocol for a test and some issues that should be paid attentioned to are also mentioned. In the end shortcomings of loading protocol for quasi-static test of structural components for building are pointed out.
