Abstract

To reduce the incidence of safety accidents during the construction of all-steel-type attached lifting scaffolds and address the research gaps in related fields, in this study a theoretical model of trajectory crossing accidents was coupled with an analysis of similar safety accidents to determine the causes of accidents in the construction of high-rise buildings using steel-type attached lifting scaffolds. To do so, a safety evaluation index system covering all steel-type attached lifting scaffolds that comprises five first-level indicators and 17 second-level indicators was established. The first-level indicators cover three risk dimensions: unsafe human behavior (personal operations), unsafe conditions (material performance, structural calculation, components and connections), and lack of management (safety management). A combined multi-agent-based modeling (MABM) method and structural entropy weight were used to calculate a comprehensive weight for better alignment of the weight calculation results with objective laws. A safety assessment model for an all-steel-type attached lifting scaffolding was constructed using grey relative Euclidean weighted correlation theory to enable the calculation of a grey-to-Euclidean weighted correlation degree that directly correlates with the degree of security. Using the established assessment model, four projects were subjected to a safety evaluation, with the results validating the model by revealing that its output was consistent with the actual security situation.

Highlights

  • All-steel-type attached lifting scaffoldings are one of the “Top Ten New Construction Technologies” [1] promoted by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China in recent years

  • Of the 56 projects investigated in Xi’an, four of the most representative all-steel-type attached lifting scaffolding projects were selected as the research sample for this case

  • All four used allsteel-type attached lifting scaffolds built by different companies

Summary

Introduction

All-steel-type attached lifting scaffoldings are one of the “Top Ten New Construction Technologies” [1] promoted by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China in recent years. These scaffoldings are superior to traditional scaffolding in terms of durability, reduced energy use and environmental protection, and rapid turnover, and they have been widely used in engineering projects in recent years. On September 10, 2011, a high-rise attachment lifting scaffolding accident at a construction site in Xi’an killed ten and seriously injured two people.
