Abstract: In order to identify critical causes and paths of tower crane accidents in construction engineering, a causation analysis method was proposed based on complex network. Firstly, accident causes were classified into 6 subsystems and 34 factors based on literature review and system thinking according to relevant laws, regulations and standards about tower crane safety. Then, with empirical data of 194 tower crane accident reports from relevant department in China, an accident causation network model of tower crane was established with causes as nodes and correlations among them as edges. Finally, statistical indicators of the model, such as degree, strength and shortest path, were calculated and analyzed, and nine critical causes, three pairs of strongly related causes and three key causation paths were identified. All these causes and paths can be taken as priorities during practice of tower crane safety control.

Key words: tower crane, safety accident cause, network model, critical cause, critical path
