Workers at elevated positions must be protected from falling or from hazardous consequences of falls. A horizontal lifeline system (HLL) is a commonly used fall arrest system (FAS) that provides protection such that when a fall does occur, the fall would be stopped promptly in a manner that prevents injury. Although the HLL systems have been in use for several decades, the design of these systems is generally completed using simple methods. One popular design method is based on a simplified energy balance analysis, which is to predict the maximum force and the maximum displacement for a fall of one person. This method may be applied to the special case of multiple persons falling only with the restrictive assumption that all people in the system must fall precisely simultaneously. It is generally regarded that this assumption is implausible and furthermore, the validity of consequent solution has not been verified because of limitation of the analysis method. The present research shows the simultaneous-fall assumption may result in an unconservative solution. In this paper, a numerical time-history method is introduced. Based on this method, two computer programs are developed: one for the single-person fall and the second for the two-person fall. Satisfactory agreement has been found in comparison with previous research results. Using these programs, an extensive parametric analysis has been conducted on the configuration of the HLL system. Suggestions for design optimization are provided.
