本文介绍了砌体拱肩的试验结果。在这一运动中，四个砌体拱肩进行准静态循环荷载。两种不同的拱肩配置进行了测试。第一种配置包括一个砌体拱肩与木材过梁，和第二种配置，砌体拱肩上的浅砌体拱。对于每种配置，两个样本进行了测试。第一个是用一个恒定的轴向载荷在拱肩进行测试，而对于第二个样本，在拱肩的轴向载荷取决于拱肩的轴向伸长。本文总结了四个测试单元的性能，测试装置，和最重要的实验结果，记录的破坏机制，开发和力-变形滞后的拱肩元件。本文还提出了一种估算砌体拱肩峰值强度的力学模型。
This paper presents the results of an experimental campaign on masonry spandrels. Within this campaign, four masonry spandrels were subjected to quasi-static cyclic loading. Two different spandrel configurations were tested. The first configuration comprised a masonry spandrel with a timber lintel, and the second configuration, a masonry spandrel on a shallow masonry arch. For each configuration, two specimens were tested. The first was tested with a constant axial load in the spandrel, while for the second specimen, the axial load in the spandrel depended on the axial elongation of the spandrel. This paper summarizes the properties of the four test units, the test setup, and the most important results from the experiments, documenting the failure mechanisms that developed and the force-deformation hysteresis of the spandrel elements. The paper also presents a mechanical model for estimating the peak strength of masonry spandrels.
