随着人们对历史建筑保护的兴趣日益增长，人们需要一种方法来分析承重的无筋砌体结构，如拱、拱顶和扶壁。虽然塑性方法，首先应用于中世纪结构的详细海曼，提供了一个有用的和直观的方法来理解性能的砌体拱和拱顶，他们的实用性在执行实际评估的结构有局限性。砌体结构中所用材料的本构关系并不总是能用刚塑性简化方法精确处理，而许多拱形砌体结构的复杂性使这些方法的应用变得困难。此外，经验研究表明，这些结构可能会受到三维效果，而不是完全解决的应用程序的塑性或弹性分析在两个维度。近年来，在发展古代砌体结构的本构关系以及将其应用于无筋砌体结构体系的分析方面取得了进展。三维有限元分析的各种公式，包括离散单元法和塑性方法也被证明是有用的。
A growing interest in the preservation of historic structures has created a need for methods for the analysis of load-bearing unreinforced masonry structures, such as arches, vaults, and buttresses. Although the plasticity methods, first applied to medieval structures in detail by Heyman, provide a useful and intuitive approach to the understanding of the behaviour of masonry arches and vaults, their usefulness in performing actual assessments of such structures has limitations. The constitutive laws of the materials used in masonry structures are not always amenable to accurate treatment by the rigid–plastic simplification, and the complexity of many vaulted masonry structures makes the application of these methods difficult. Moreover, empirical studies have shown that these structures may be subject to three-dimensional effects that are not entirely addressed by the application of plastic or elastic analysis in two dimensions. Progress has been made recently in the development of constitutive laws for ancient masonry structures and in the application of these to the analysis of unreinforced masonry structural systems. Various formulations of three-dimensional finite element analysis, including discrete element methods, and plasticity methods have also proven useful.
