THE ANALYSIS OF H-SHAPED HORIZONTAL LIFELINE FALL PROTECTION SYSTEM

by ZHANG, SHIQIAO

Abstract (Summary)
To protect workers at elevated positions from falling, many fall protection systems are used. Generally, fall protection systems are divided into two categories: fall restraint systems and fall arresting systems. In this thesis, emphasis is given to the H-shaped horizontal lifeline (HHLL) fall protection system, which belongs in the fall arresting category. Various fall protection systems are first introduced and the advantages and disadvantages are compared. Explanations about the competitiveness of the HHLL system and the importance of giving attention to the HHLL system are stated followed by the basic cable theories, which constitutes the background of the thesis. The force and displacement analysis of the HHLL system proceeds in several stages. In the first stage, single-span HHLL systems with different configurations are analyzed with a simplified consideration of the cable self-weight. In the second stage, a refined method is followed because the self-weight is found to have much effect on the analysis. In the refined method, the self-weight is accurately calculated and the practice of setting up systems on the site is considered for detailed analysis. In the third stage, simple multi-span systems and four selected configurations of overlapped-cable multi-span systems are analyzed and compared. Finally, a system configuration is recommended based on the evaluation of the overall system performance.
