Optimal Selection of High-Performance Concrete for Post-Tensioned Girder Bridge Using Advanced Hybrid MCDA Method

Abstract

The selection of material solutions is a basic decision-making problem that occurs in engineering issues. It affects the entire life cycle of a building structure, its safe use, maintenance costs, and a need to meet requirements for sustainable development, including recycling. This paper aims at selection of the optimum composition of HPC designed for monolithic girder structures of post-tension bridges. For the analysis, a set of 12 new-generation concretes (HPC) was designed, made, and tested. A full-scope set of evaluation criteria was created and then the optimal alternative was selected. For this purpose, an advanced hybrid algorithm combining EA FAHP (Extent Analysis Fuzzy Analytic Hierarchy Process) and FuzzyTOPSIS (Fuzzy Technique for Order Preference by Similarity to an Ideal Solution) methods was used. The obtained results indicate a possibility for the practical application of the proposed algorithm by decision-making engineering staff. It can also be the basis for further research on application compared to other material and design solutions and, depending on the issue, different combination of aggregated methods.

Sustainability Assessment of a Low-Income Building: A BIM-LCSA-FAHP-Based Analysis

“…Therefore, several researchers conclude that the correct selection of materials is one of the simplest and most efficient ways to incorporate sustainability in the construction industry [25,29,30]. Despite the relevance of optimizing the construction materials selection process, currently, in practice, this is still primarily done empirically, based on the engineers' knowledge and experience, rather than numerical approaches [30][31][32]. However, when associated with the lack of experience of the responsible professional, this heuristic approach prevents the available alternatives from being objectively compared [25,33], and the lowest price ends up prevailing as the most important choice criterion.…”

“…However, when associated with the lack of experience of the responsible professional, this heuristic approach prevents the available alternatives from being objectively compared [25,33], and the lowest price ends up prevailing as the most important choice criterion. Therefore, it is essential to develop a systematic decision model that helps team members to choose the most advantageous materials, based on well-defined, sustainable, and unambiguous criteria [23,32].…”

“…Choosing between different construction materials that will provide the best economic, environmental, and social performance when applied together is a complex multicriteria decision-making (MCDM) problem, requiring interdisciplinary knowledge [28,32,51]. A multicriteria analysis is required when dealing with multi-faceted events by combining qualitative and quantitative techniques [52,53], that include the consideration of multiple criteria simultaneously [54,55].…”

“…Singh et al [74] integrated FAHP and TOPSIS in the selection of composite materials applied to structural elements. A similar strategy was presented by Janowska-Renkas et al [32], who used FEAHP and Fuzzy-TOPSIS to select the best high-performance concrete for post-tension bridges. Mayhoub et al [27] applied AHP in the development of a new evaluation framework based on four green building rating systems for selecting sustainable façade materials.…”

Bridge Construction Quality Evaluation Based on Combination Weighting Method- Technique for Order Preference by Similarity to an Ideal Solution Theory

“…By conducting a series of static experiments on stainless steel reinforced concrete columns, Li Qingfu et al proposed a bearing capacity formula that should be followed when stainless steel reinforcement is used in bridge engineering, which lays the foundation for bridge engineering construction under corrosive environments [19]. El żbieta Janowska-Renkas et al provided a concrete material selection method based on the improved hybrid MCDA method, which is of great significance for improving the construction technology level of high-performance concrete post-tensioned girder bridges [20].…”
