摘要

基于构件标准试验的抗火试验方法很难考虑非受火构件对受火构件的约束效应，也难以反映受火构件对整体结构抗火性能的影响，而正在兴起的抗火混合试验方法是解决上述问题的一条重要途径。本文首先简述传统结构抗火试验方法及其面临的问题，进一步阐述了抗震混合试验与抗火混合试验的关系，然后从试验流程原理、典型试验装置及对应力学边界条件、试验子结构选取与数据交换、不同试验方法的结果对比等方面较为系统地介绍了第一代抗火混合试验，并简要介绍了正在进行中的第二代抗火混合试验系统及其特点，最后总结了抗火混合试验中有待进一步深入研究的几个关键科学问题。

Abstract

Fire test method based on the standard is difficult to consider the restraining effect of the surrounding unfired components on the fired components

and it is also difficult to reflect the influence of the fired components on the fire resistance performance of the overall structure. The emerging hybrid fire testing may be an important way to solve the above problems. This paper first briefly describes the traditional structural fire resistance test methods and their defects

and further expounds the relationship between the hybrid seismic testing and the hybrid fire testing. Secondly

the first generation hybrid fire test method is systematically introduced from the aspects of the test process and principle

typical test equipment and corresponding mechanical boundary conditions

physical substructure selection and data exchange

and the comparison of results from different test methods. Then the second-generation hybrid fire testing system and its characteristics are introduced briefly. Finally

several key scientific issues to be further studied in the hybrid fire testing are summarized.
