Safety decision analysis of collapse accident based on “accident tree–analytic hierarchy process”

Abstract To reduce the hazards of collapse accidents in construction process and to ensure that lives, health, property workers are protected, this study used theory safety system engineering identify accidents, analyze hazards, predict consequences, evaluate systemic risks, effects improve them. At same time, risk factors were evaluated qualitatively quantitatively by using analysis methods fault tree (FTA) analytic hierarchy (AHP). Finally, according evaluation results, main causing found; provided a reliable practical basis for prevention accidents. Then, decisive factors, corresponding measures taken advance achieve aim preventing controlling The results show equipment maintenance, material inspection, site management play an important role
