Research on safety risk assessment of large span steel truss stadiums construction based on GCD-FER
Large stadiums often use large-span steel trusses (LSST) as the support structure for their roofs. Due to their large size and heavy weight,as well as the cumbersome splicing process,LSSTs are prone to safety accidents during construction,resulting in significant casualties and economic losses. Therefore,it is urgent to explore and evaluate the safety risks of LSST stadiums construction (LSSTSC) to better prevent safety accidents.This article was based on "personnel-material & equipment-technology-environment-management" framework,and utilized literature review and expert discussions to identify safety risks. It integrated grey correlation degree (GCD) and fuzzy evidence reasoning (FER) to establish a safety risk assessment method,and applied it to the ZN University gymnasium project to conduct a case study. It was found that the LSSTSC safety risk list includes first-level safety risks such as construction personnel,construction materials and equipment,construction technology,construction environment,and construction management,as well as 21 second-level safety risks. The safety risk list and assessment method can be used to identify relevant safety risks and assess the degree of safety risks at all levels. The case study revealed that the construction safety risk of the ZN University gymnasium project is classified as medium-level risk. The construction management risk and construction technology risk are identified as significant first-level safety risks,and the incomplete steel truss high-altitude splicing technology is a significant second-level safety risk. This study can enrich the theoretical knowledge of safety risk assessment for LSSTSC,and provide reference for safety management personnel to carry out on-site scientific and effective safety management.
