确定通过有限元分析估计的结构行为不仅需要深入了解其几何形状和动态特性，还需要实验验证来证实结构特征的充分性。目前大多数结构识别技术都是基于线性方法，需要许多测量点和/或相对简单的结构。由于有限元法的困难和其结果的实验证实，复杂结构在某种程度上仍然是一个未探索的领域。本研究提出了使用粒子运动计算应用到每个结构的振动模式，以提高其动态特性的识别，并将其应用到哥特式大教堂的帕尔马德马略卡岛（西班牙）。
Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).
