摘　　要：近年来,对轻型钢框架房屋在地震作用下的反应进行了很多重要的研究。几乎所有的研究都是将这些结构特征化,然后进行试验和理论分析来研究其在地震下的反应以及墙板的性能。通常情况下,墙板的整体性能是主要的研究目标。然而,根据试验现象来看,墙板的整体性能是由连接件的性能控制的。这些连接件包括板和板之间的连接件以及墙板和钢框架之间的连接件。另外,三维房屋结构的整体性能受非结构构件影响很大,这在当前的设计方法中是没有考虑的。本文回顾了近年来PolitehnicaUniversityofTimisoara由作者主持的研究成果,该成果以衡量轻型钢框架房屋的性能及特征为目标,致力于这种结构的具体特征的设计。本文还介绍了剪力墙板的足尺单调及循环加载试验,连接节点的试验以及对正在建造中的房屋的现场环境振动试验。In recent years important research activity has been undertaken in order to evaluate the earthquake performance of light gauge steel framed house structures. Almost all studies approach the problem of seismic response of these structures and the performance of wall panels by characterizing, experimentally and numerically. Usually, the overall behaviour of wall panels is mainly addressed. However, according to experimental evidences, the performance of the wall panels, as a whole, is governed by the performance of the connectors e. g. ： sheeting-to-sheeting connectors, and sheeting to framing connectors. On the other hand the global behaviour of the 3D structure of the house is significantly influenced by non-structural elements, traditionally not considered in the design procedures. Present paper summarizes the research activity carried out last years at the Politehnica University of Timisoara, under the coordination of the author, on the aim to evaluate the performance and to characterise for design purpose the specific features of these structures. Monotonic and cyclic tests on full scale shear panels, test on connection details and in-situ ambiental vibration tests on a house under construction are reviewed in the following paper.
