摘要

试验研究包括超高性能钢纤维增强混凝土(UHPFRC)的设计和生产。在实验室环境下研究了UHPFRC的物理和机械性能。为了研究UHPFR混凝土的性能,使用了三种类型的混凝土和70多个样品。随后,制作了样品来测试锚的承载性能。共创建了6块混凝土板,共108个预安装锚样和6块混凝土板,共108个后安装化学锚样。测试结果的分析包括所有单独的结果,以及锚的拉伸载荷能力和其他参数之间关系的定义。为了准确地确定所调查因素的个体影响及其综合影响,除常规统计数值研究外,还使用了析因实验和人工神经网络。这两种方法都有各自的优点。所得结果在某些部分显示出匹配。由于处理数据的方式不同,它们之间也存在显著差异。

Determination of the effects of the rebar-cement bond parameters variation in UHPFRC using Fa and ANN
The experimental study included the design and production of ultra-high-performance steel fiber-reinforced concrete (UHPFRC). The physical and mechanical properties of UHPFRC were investigated in a laboratory setting. To investigate the properties of UHPFR concrete, three types of concrete and over 70 samples were used. Following that, samples were created to test the anchors' load-bearing performance. Six concrete slabs with a total of 108 pre-installed anchor samples and six concrete slabs with 108 post-installed chemical anchor samples were created. The analysis of the test findings comprised all individual results as well as the definition of the relationship between the anchor's tensile load capacity and other parameters. To accurately determine the individual influence of the investigated factors as well as their combined impact, a factorial experiment, and artificial neural networks were used in addition to normal statistical numerical studies. It was determined that both approaches offer advantages. The results obtained show matches in certain parts. Due to the way data is processed in different ways, there are also significant differences between them.

期刊介绍: Science of Sintering is a unique journal in the field of science and technology of sintering. Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published. Science of Sintering journal is published four times a year. Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
