摘要

在过去的几年里,许多努力都集中在将不可生物降解的废物作为水泥基材料中天然骨料的部分替代品和可持续替代品。目前,橡胶混凝土被认为是最重要的绿色混凝土材料之一,它是用旧轮胎中的橡胶颗粒代替混凝土混合物中的天然骨料而生产的。除了在可持续性和废物管理方面的重要性外,这种材料的主要优点还在于橡胶具有相当大的阻尼振动的能力,当用于钢筋混凝土结构时,可以显著增强其能量耗散和振动性能。目前,文献中有许多实验发现,为橡胶混凝土的动力性能提供了一个有趣的观点。另一方面,目前还缺乏对这些发现进行收集、解释和数值研究,以提供一些相关性并构建可靠的橡胶混凝土动态性能预测模型的研究。因此,本研究旨在提出橡胶混凝土动态性能的预测方法。作为研究的一部分,多元线性回归和人工神经网络将用于创建动态弹性模量,阻尼比和固有频率的预测模型。

Prediction of the dynamic properties in rubberized concrete
Throughout the previous years, many efforts focused on incorporating non-biodegradable wastes as a partial replacement and sustainable alternative for natural aggregates in cement-based materials. Currently, rubberized concrete is considered one of the most important green concrete materials produced by replacing natural aggregates with rubber particles from old tires in a concrete mixture. The main benefits of this material, in addition to its importance in sustainability and waste management, comes from the ability of rubber to considerably damp vibrations, which, when used in reinforced concrete structures, can significantly enhance its energy dissipation and vibration behavior. Nowadays, the literature has many experimental findings that provide an interesting view of rubberized concrete's dynamic behavior. On the other hand, it still lacks research that collects, interprets, and numerically investigates these findings to provide some correlations and construct reliable prediction models for rubberized concrete's dynamic properties. Therefore, this study is intended to propose prediction approaches for the dynamic properties of rubberized concrete. As a part of the study, multiple linear regression and artificial neural networks will be used to create prediction models for dynamic modulus of elasticity, damping ratio, and natural frequency.
