Abstract

AbstractThe paper looks at a novel structural solution to sidewalks. The proposed system consists of a box element as a substructure and a concrete slab with openings for rainwater infiltration. Such a design will make the sidewalk comfortable for pedestrians with motor impairments, friendly for urban tree root systems and durable. The article provides stress and strain calculations for the variants of the new design. We used the finite element method for the analysis. The results confirm that the proposed variants meet the assumed strength criteria and can therefore be used in the next research steps, that is, permeability tests, rain-water retention simulations, laboratory testing.Highlights Concrete paving slab with environmental approach.Concrete paving slab for people with motor disabilities.The first study implementing FEM method supported by the Barcelona model to analyse stresses and strains in sidewalk pavement.KEYWORDS: Concrete paving slabpermeable concretepedestrians with motor disabilitiesurban treesstress–strain data Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by Narodowe Centrum Badań„ i Rozwoju [grant number Rzeczy są … dla ludzi/0052/2020-00 entitled Pavepro].

为保证运动障碍者行走舒适性而设计的混凝土人行道系统的承载能力分析

摘要:本文研究了一种新的人行道结构解决方案。提议的系统由一个作为下层结构的盒子元素和一个带有雨水渗透开口的混凝土板组成。这样的设计将使人行道对运动障碍的行人舒适，对城市树根系统友好，并且耐用。本文提供了新设计的各种变体的应力和应变计算。我们采用有限元法进行分析。结果证实，所提出的变体符合假定的强度标准，因此可以用于下一步的研究步骤，即渗透性测试，雨水保持模拟和实验室测试。突出混凝土铺路板的环保方法。为运动障碍人士而设的混凝土铺路板。首次采用巴塞罗那模型支持的有限元方法对人行道路面进行应力应变分析。关键词:混凝土铺装板透水混凝土运动障碍行人城市树木应力应变数据披露声明作者未报告潜在的利益冲突。本研究得到了Narodowe Centrum badawa“i Rozwoju”的支持[资助号:Rzeczy stoy…dla ludzi/0052/2020-00标题:Pavepro]。

期刊介绍： The international journal Road Materials and Pavement Design welcomes contributions on mechanical, thermal, chemical and/or physical properties and characteristics of bitumens, additives, bituminous mixes, asphalt concrete, cement concrete, unbound granular materials, soils, geo-composites, new and innovative materials, as well as mix design, soil stabilization, and environmental aspects of handling and re-use of road materials. The Journal also intends to offer a platform for the publication of research of immediate interest regarding design and modeling of pavement behavior and performance, structural evaluation, stress, strain and thermal characterization and/or calculation, vehicle/road interaction, climatic effects and numerical and analytical modeling. The different layers of the road, including the soil, are considered. Emerging topics, such as new sensing methods, machine learning, smart materials and smart city pavement infrastructure are also encouraged. Contributions in the areas of airfield pavements and rail track infrastructures as well as new emerging modes of surface transportation are also welcome.
