Abstract: Steel tubular scaffold with couplers is the most widely used scaffold system in construction site of China. But because of its low safety performance and lacking of supervision, these problems lead to massive collapse in the process of long-term using and became potential risks which are difficult to eliminate. The factors bring about collapse accident of steel tubular scaffold with couplers come from many aspects, including production, design, using and regulation. These factors present a diverse and interconnected situation. With the improvement of structure calculation theory and strengthening of policy guidance, an increasing number of scientific evaluation methods have been applied in collapse accident analysis of steel tubular scaffold with couplers. In order to meet complex engineering safety problems and the requirements of dynamic quantitative analysis with multiple factors, the comprehensive analysis which has many advantages will become the mainstream of collapse accident analysis of steel tubular scaffold with couplers in the future.
