Influence of Stairway Handrail Height on the Ability to Generate Stabilizing Forces and Moments

Abstract

An experimental study was performed investigating the influence of handrail height on the ability of stairway users to generate stabilizing forces and moments, with the aim of improving stairway safety by developing better handrail design standards. The experiments involved measurement of the maximum forces and moments that subjects were able to exert on a handrail while they stood stationary in an upright position. Two age groups were tested: young (20 to 45 years) and elderly (59 years and over), with a total of 35 subjects. All subjects showed a strong linear dependence on handrail height in generating stabilizing forces and moments. Ability to generate forward/backward forces and forward/backward moments increased linearly with increasing handrail height. Ability to generate upward force decreased linearly with increasing handrail height. Based on the results, an optimal design range for handrail height was estimated.
