历史上的无筋砌体建筑通常包括诸如承重无筋砌体拱顶及其支撑框架的墩、填充物、扶壁和墙壁等特征。这种建筑物的砌体拱顶是最脆弱的结构部件之一，当然也是最具挑战性的分析。在过去的三十年里，有限元（FE）分析的多功能性，包括各种本构关系，以及几乎所有的几何配置，导致了广泛使用的有限元方法分析复杂的无筋砌体结构。然而，有限元模型的准确性取决于其输入参数，并且在定义有限元模型输入参数时存在两个根本挑战：（1）材料属性和（2）支撑条件。在定义这两个方面的有限元模型的困难来自缺乏知识的砌体行为的共同工程的理解。因此，工程师无法确定这些FE模型输入参数，并且不可避免地将不确定性引入FE模型。
Historical unreinforced masonry buildings often include features such as load bearing unreinforced masonry vaults and their supporting framework of piers, fill, buttresses, and walls. The masonry vaults of such buildings are among the most vulnerable structural components and certainly among the most challenging to analyze. The versatility of finite element (FE) analyses in incorporating various constitutive laws, as well as practically all geometric configurations, has resulted in the widespread use of the FE method for the analysis of complex unreinforced masonry structures over the last three decades. However, an FE model is only as accurate as its input parameters, and there are two fundamental challenges while defining FE model input parameters: (1) material properties and (2) support conditions. The difficulties in defining these two aspects of the FE model arise from the lack of knowledge in the common engineering understanding of masonry behavior. As a result, engineers are unable to define these FE model input parameters with certainty, and, inevitably, uncertainties are introduced to the FE model.
