This paper discusses the origins of torsion and its effect on the response of structures with a focus on the contribution of experimental data. The fact that torsion increases the stresses in structures, augmenting strain and damage during earthquakes, was confirmed in the 1960s. Over the years, the torsional response of structures has mainly been analysed through numerical studies, because few buildings are equipped with translational sensors, and even fewer are equipped with rotational sensors. This is likely to change as building instrumentation becomes more widespread and new generations of rotational sensors are developed. Therefore, this paper focusses on a number of scientific questions concerning the rotational response of structures during earthquakes and the contribution of experimental data to the understanding of this phenomenon.
本文讨论了扭转的起源及其对结构响应的影响，重点关注实验数据的贡献。扭转会增加结构中的应力，在地震期间加剧应变和破坏，这一事实在20世纪60年代得到了证实。多年来，结构的扭转响应主要通过数值研究进行分析，因为配备平移传感器的建筑物很少，配备旋转传感器的更少。随着建筑仪器的普及和新一代旋转传感器的开发，这种情况可能会改变。因此，本文重点关注一些与地震期间结构的旋转响应以及实验数据对理解这一现象的贡献有关的科学问题。
