Data underlying the article: A Strategy for Material Characterisation of Multi-wythe Masonry Infrastructure: Preliminary Study

To provide insights on how to characterise multi-wythe masonry infrastructure, a pilot study has been started at Delft University of Technology in 2022 with the characterisation of a bridge’s pillar built in 1882 in Amsterdam (Bridge 41). Samples were extracted in the portion of masonry above water level and different samples through the thickness direction of the masonry wall were collected. Various mechanical tests, including tests on cores and on standard rectangular samples (e.g. couplets, prisms, triplets) were performed. In this dataset, the outcome of compressive tests on cores and prisms, splitting tests on cores, shear-compression tests on triplets, and bond wrench tests on couplets, are presented to characterise compressive properties of masonry as well as shear and bond properties of brick-mortar interfaces. The scope is to identify if it exists a variation of the mechanical properties throughout the thickness and to discuss the suitability of the core testing method for multi-wythe masonry in city infrastructure.

为明确多层砌体（multi-wythe masonry）基础设施的表征方法，代尔夫特理工大学（Delft University of Technology）于2022年启动一项试点研究，对阿姆斯特丹41号桥（Bridge 41）这座建于1882年的桥墩开展性能表征工作。研究人员从桥墩水位以上的砌体区段取样，并沿砌体墙体的厚度方向采集了多组差异化试样。本次研究开展了多类力学性能测试，涵盖岩心试样（core）测试与标准矩形试样测试，其中标准矩形试样包括双砖试样（couplets）、棱柱试样（prisms）、三砖试样（triplets）。本数据集收录了如下试验的结果：岩心与棱柱试样的抗压试验、岩心试样劈裂试验（splitting tests）、三砖试样剪压试验（shear-compression tests）以及双砖试样粘结扳手试验（bond wrench tests），用于表征砌体的抗压性能，同时明确砖-砂浆界面（brick-mortar interfaces）的抗剪与粘结性能。本研究旨在探明沿墙体厚度方向力学性能是否存在变化，并探讨岩心测试方法应用于城市基础设施多层砌体的适用性。
