镶嵌是重复的2D几何形状的图案，其形成没有间隙或重叠的布置。虽然通常用于建筑的视觉吸引力，镶嵌只是最近才受到关注，其适用性的结构，镶嵌结构建筑（TeSA）系统。由于TeSA系统由重复的离散件（瓦片）组成，镶嵌结构构件具有几个潜在的好处，包括自动化制造和施工，结构损坏的定位和可修复性，可调结构行为和美学价值。本文介绍了小规模（约20 mm宽× 75 mm高× 300 mm长）TeSA梁的实验，这些梁是由3D打印的镶嵌瓷砖制成的，然后加载至失效。荷载-位移响应和破坏模式的六个梁试样，每个具有不同的镶嵌图案。刚度，强度和故障模式之间的不同模式进行比较。研究结果为如何设计棋盘格结构以实现所需的结构响应提供了见解。虽然镶嵌结构的概念仍处于萌芽状态，本文介绍了这一概念，论证和讨论了它的潜力，并提出了一些关于结构性能和设计的重要意见。
Tessellations are patterns of repeating 2D geometric shapes that form an arrangement without gaps or overlaps. Although commonly used for their visual appeal in architecture, tessellations have only recently received attention for their applicability to structures as tessellated structural-architectural (TeSA) systems. Because TeSA systems are composed of repeating discrete pieces (tiles), tessellated structural members have several potential benefits including automated fabrication and construction, localization and repairability of structural damage, tunable structural behavior, and esthetic value. This paper presents experiments in which small-scale (approximately 20 mm wide × 75 mm tall × 300 mm long) TeSA beams were fabricated from 3D printed tessellated tiles and then loaded to failure. Load-displacement response and failure mode are presented for six beam specimens, each having a different tessellated pattern. Stiffness, strength, and failure mode are compared between the different patterns. The results provide insights into how to design tessellated structures to achieve a desired structural response. While the notion of tessellated structures is still in its nascency, this paper introduces the concept, demonstrates and discusses its potential, and makes some critical observations about structural behavior and design.
