The Safety Evaluation of Steel Tubular Scaffold with Couplers Based on Analytic Hierarchy Process-Fuzzy Comprehensive Evaluation

In the water conservancy and hydropower project construction site, the scaffolding plays an important role in the construction site and the characters of the construction are a long period, complexity and frequent operation and so on. In the traditional methods, we uses qualitative and simple quantitative research methods to make the safety evaluation of the scaffolding. Those quantitative methods are affected by subjective judgment, having no scientific evidence. In accordance with the real example, this article makes the scaffolding as a whole to analyze, using the AHP-fuzzy comprehensive safety evaluation method and verifying the former method by fuzzy pattern recognition in the ending of the passage and hoping that it has reference for the project practice.
