Abstract

This study proposes the design of modular structural geopolymer concrete elements incorporating decommissioned flexible flowlines. To evaluate and assess the feasibility of the proposed modular structural elements, this study aims to investigate its feasibility from the perspectives of sustainability including cost analysis, circular economy (CE) analysis and CO2 emission estimate. Moreover, a series of numerical analyses using finite element modelling (FEM) is conducted to provide insight into the mechanical behaviour of such modular columns and beams. Apart from the cost-saving, CE and social impact benefits of the proposed elements, the results indicate that modular structural elements incorporating flowline have shown very high axial, shear and flexural capacities, which make them suitable to be used in high-rising buildings, bridges, etc. The proposed elements can be a solution to decommission and reuse the flexible flowline on a large scale in construction.
模块化结构元素结合了退役的柔性管线和地聚合物混凝土
本研究提出了结合退役柔性管线的模块化结构地聚合物混凝土构件的设计。本研究从可持续性的角度,包括成本分析、循环经济(CE)分析和二氧化碳排放估算,对所提出的模块化结构构件的可行性进行评估和评估。此外,使用有限元模型(FEM)进行了一系列数值分析,以深入了解这种模块化柱和梁的力学行为。除了成本节约、环境效益和社会影响效益外,研究结果还表明,包含流水线的模块化结构单元具有很高的轴向、剪切和抗弯能力,适合用于高层建筑、桥梁等。所提出的元件可以解决大规模施工中柔性管线的退役和再利用问题。
