Abstract

The purpose of this study was to measure the dynamic tension force between the apparatus and the hanging equipment of five aerial circus apparatuses and to recommend minimal loading requirements in rigging and design. The forces generated by different acrobatic movements were measured and synchronized with video recordings. Sixteen students of the National Circus School of Montréal (Canada) participated in the study. The maximal forces were analyzed and characterized with respect to the discipline, the type of movement and the schooling level of the student. The maximal force measured was 5.3 kN performed in the discipline of aerial straps, equivalent to 7.9 times the bodyweight of the performer. A minimal breaking strength of 22 kN for the hanging point and all the equipments holding the rig is recommended. A minimal breaking strength of 22 kN for straps, 17 kN for rope and 12 kN for silk, aerial hoop and dance trapeze is recommended.
