A methodology for evaluation of the use of advanced composites in structural civil engineering applications

Abstract

The objective of this research was to develop a tool for evaluating the potential use of advanced materials in structural civil engineering applications. A multi-criteria systematic approach based on the analytical hierarchy process (AHP) was developed to assist decision-makers in evaluating the use of advanced materials. This study provides decision-makers with the means to evaluate the use of various structural materials based on specific applications, optimizing the use of limited resources. One of the key elements of the model is the ability to handle complex problems and alternatives with multiple objectives. This tool was applied to test the use of advanced composite materials in the repair of deteriorated and damaged bridge columns. The purpose of the study is to respond to the need to repair, strengthen, and retrofit existing structures, and to avoid or reduce such need when planning for new structures. Tools to evaluate and select an optimal structural material are generally outdated, and ineffective. This in turn limits the selection to popular conventional materials, foregoing the potential benefit of using new structural materials. The scope of this research is limited to transportation infrastructure, construction and repairs.
