A finite element based framework that formulates an adaptive multiresolution multiscale technique is presented, with the goal of both accurately and efficiently simulating large masonry structures. In order to find a compromise between accuracy and computational efficiency a scale embedding multiscale model where both macro- and microscale elements come into play is proposed, combining the advantages both have to offer. This theory is tested and compared with an equivalent microscale model to demonstrate that its accuracy rivals a microscale approach, while at the same time having a higher computational efficiency. The developed multiscale model is compared to its underlying microscale model in a couple of selected example structures, ranging from small to large scale unreinforced masonry walls with openings. An application in the form of soil subsidence is explored, showing a potential for extended applications of this type of modeling.

提出了一种基于有限元的框架，该框架制定了一种自适应的多分辨率多尺度技术，其目的是准确而有效地模拟大型砖石结构。为了找到准确性和计算效率之间的折衷，提出了一种规模嵌入多尺度模型，其中宏观和微观尺度元素均在其中发挥作用，并结合了两者必须提供的优势。对这一理论进行了测试，并将其与等效的微尺度模型进行比较，以证明其准确性可与微尺度方法相媲美，同时具有更高的计算效率。在几个选定的示例结构中，将开发的多尺度模型与其基础的微观模型进行了比较，这些结构从小到大的无开口砌体墙都有开口。
