Abstract
Despite the growing incorporation of additive manufacturing in the construction industry, a significant gap persists in the availability of design guidelines and comprehensive structural assessments for 3D-printed components. This research employs experimental methods to evaluate the performance of large-scale hollow unreinforced 3D-printed masonry walls under axial compressive load. Furthermore, a design methodology tailored for 3D-printed masonry walls under compressive loads is proposed in compliance with both American and Canadian masonry standards. This methodology is supported by the application of linear elastic 3D finite element analysis. Moreover, supplementary insights into material behavior are garnered through the examination of small specimens extracted from an additional 3D-printed wall. The results reveal that 3D printing reduces stiffness and compressive strength. The 3D-printed infills played an important role in redistributing stress after cracking. All full-scale 3D-printed masonry walls examined in this research exceeded the performance criteria set by the American masonry standard for load-bearing walls.
尽管增材制造技术越来越多地应用于建筑行业,但在三维打印构件的设计指南和全面结构评估方面仍存在巨大差距。本研究采用实验方法评估了大型空心非加固 3D 打印砌体墙在轴向压缩荷载作用下的性能。此外,还根据美国和加拿大的砌体标准,提出了在压缩荷载作用下为 3D 打印砌体墙量身定制的设计方法。线性弹性三维有限元分析的应用为该方法提供了支持。此外,还通过对从另外一个 3D 打印墙体中提取的小试样进行检查,获得了对材料行为的补充见解。结果显示,三维打印降低了刚度和抗压强度。三维打印填充物在开裂后重新分配应力方面发挥了重要作用。本研究中检测的所有全尺寸 3D 打印砌体墙均超过了美国砌体承重墙标准规定的性能标准。
