ABSTRACT

The design of brick masonry vaults has frequently been one of the main topics of historical construction handbooks, where also the orientation of the blocks was an examined issue. However, the influence of brick-texture has not yet been thoroughly investigated computationally. In the present paper the static behavior of masonry vaults of different shapes (barrel, pavilion, and cross vaults), was studied by analyzing and integrating two points of view: one historical and the other computational. First, the instructions provided by ancient documents were described. Then, a Non-Smooth Contact Dynamics Software was used to model vaults with different brick patterns suggested in the past. The vaults were studied with self-weight to observe load descent. Then, a concentrated force was added up to collapse. The analyses show how the load descent and load-bearing capacity are influenced by the brick pattern. Finally, the results of the various analyses were compared with the insights of the past.

摘要

砖砌拱顶的设计经常是历史建筑手册的主要主题之一，其中砌块的方向也是一个检查问题。然而，砖纹理的影响尚未在计算上得到彻底研究。在本文中，通过分析和整合两种观点：一种是历史的，另一种是计算的，研究了不同形状的砖石拱顶（桶形、亭子和十字形拱顶）的静态行为。首先，描述了古代文献提供的指示。然后，使用非平滑接触动力学软件对具有过去建议的不同砖图案的拱顶进行建模。用自重研究拱顶以观察负载下降。然后，一个集中的力量加起来，崩溃了。分析显示负载下降和承载能力如何受砖图案的影响。最后，将各种分析的结果与过去的见解进行了比较。
