本文介绍了一种新的模块化剪力墙体系，该体系具有可替换性和极限荷载后的回弹能力，并具有一定的建筑吸引力。这些墙被称为镶嵌结构建筑(TESA)墙，因为它们由具有重复形状(镶嵌)的联锁瓷砖(模块)组成，旨在满足结构和建筑需求。在TESA系统中，瓷砖的不连续性可能会将损坏包含在离散的单元内。这有助于加快结构修复和重新使用，并减少随之而来的服务中断造成的财务损失。TESA系统的瓷砖可以在一个或两个方向上互锁，并可以包括自定心后张拉。本研究基于(1)室内墙体试验和(2)特萨剪力墙的有限元模型，对单向联锁的特萨剪力墙的损伤进行记录和量化。考虑的特萨墙由钢筋混凝土瓷砖组成，并有自定心后张拉。联锁瓷砖不需要与相邻瓷砖进行机械连接。根据通过测试观察到的损坏瓷砖的数量和通过分析获得的损坏瓷砖数量来量化墙壁损坏。在开源分析软件OpenSees中对特萨剪力墙进行了有限元分析。进行了静力推覆分析，得到了力-位移关系和随后的损伤。提出了一个计算突出漂移处损伤概率的框架，该框架考虑了瓷砖-界面属性、建模方法和外加载荷的不确定性。在漂移0.87%时，一维联锁TESA墙的无损伤概率为9%，轻微损伤概率为91%。该框架可用于生成特萨墙体的脆性函数。
This paper introduces a new modular shear wall system designed for replaceability and resilience after extreme loading as well as architectural appeal. The walls are called tessellated structural-architectural (TeSA) walls because they consist of interlocking tiles (modules) with repetitive shapes (tessellations) and are intended to satisfy both structural and architectural demands. In TeSA systems, tile discontinuities may be able to contain damage within discrete units. This can facilitate quicker structural repair and reoccupation, and reduction of ensuing financial losses from service interruptions. Tiles of TeSA systems can be interlocking in one or two directions and can incorporate self-centering post-tensioning. This study focuses on documenting and quantifying damage in TeSA shear walls with tiles interlocking in one direction based on (1) laboratory tests performed on walls and (2) finite element modeling of TeSA walls. The considered TeSA walls consisted of reinforced concrete tiles and had self-centering post-tensioning. The interlocking tiles did not need mechanical connections to adjacent tiles. Wall damage was quantified in terms of the number of damaged tiles as observed through testing and obtained through analyses. Finite element analyses of the TeSA shear wall were performed in open-source analysis software (OpenSees). Static pushover analyses were performed to obtain force-displacement relationship and ensuing damage. A framework for calculating probability of damage at salient drifts is presented considering uncertainties in tile-interface properties, modeling approach, and applied loading. The 1-D interlocking TeSA wall had a 9% probability of no damage and 91% probability of slight damage at the drift of 0.87%. The framework can be used to generate fragility functions for the TeSA wall.
