本文讨论了一个全面的振动台试验活动的主要结果进行的主持下，欧盟资助的研究项目SERA，其目的是调查的三叶砌体墙的抗震性能弱石灰砂浆接缝。这些砌体墙广泛存在于地中海地区的地震多发区，因此评估其动态行为是对众多历史中心进行地震易损性评估的重要前提。本文的第一部分是对墙体构件材料的力学性能进行了初步研究，并进行了一系列的室内试验。的结果是特别感兴趣的砂浆和填充材料的特性，旨在重现低强度，通常是在旧的砖石建筑。接下来介绍了进行测试的砌体墙的设计和测试装置。所施加的加载协议由地面运动记录的水平分量组成，该地面运动记录反复施加到振动台上，强度逐渐增加。最后对实验测试的主要结果进行了讨论。给出了地震动序列的损伤模式、位移比和基底剪力。结果还讨论了通过动态能力曲线，显示了不同的极限状态的实现与地面运动强度。一组非线性数值模拟，静态和动态，使用三维有限元模型的墙壁验证的实验研究，因为他们报告与实验测试吻合良好，并表现出稳定的数值行为。
This paper discusses the main results of a full-scale shaking table test campaign carried out under the auspices of the EU funded research project SERA, whose objective is to investigate the seismic performance of three-leaf masonry walls with weak lime-mortar joints. These masonry walls are widely found in seismic prone regions in the Mediterranean area, thus assessing their behaviour under dynamic actions is an important pre-requisite for the seismic vulnerability evaluation of a plethora of historical centres. The first part of the paper presents a preliminary study on the mechanical properties of the wall component materials that was carried out through anad-hocexperimental campaign. The outcomes are of particular interest for the characterization of the mortar and of the infill materials, that were designed to reproduce the low strength that is typically found in old masonry buildings. The design of the masonry wall that was tested and the test set-up are presented next. The applied loading protocol consisted of the horizontal component of a ground motion record that is repeatedly applied to the shaking table with increasing intensity. Finally, the main results of the experimental test are discussed. The damage patterns, drift ratios and base shear are presented for the ground motion sequence. The results are also discussed through a dynamic capacity curve that shows the attainment of different limit states with increasing ground motion intensity. A set of nonlinear numerical simulations, both static and dynamic, using a 3D FE model of the wall verify the experimental study as they report good agreement with the experimental tests and exhibit stable numerical behaviour.
