Muscular strain and fatigue are always associated with prolonged standing and causing an increased risk of musculoskeletal disorders among surgeons. Lack of ergonomic awareness and aging in the population also further increases the risk of musculoskeletal disorders. This paper analysed the design of a walkable chair that straps to surgeons’ lower extremities to support their weight while performing surgical operations in a half-sitting posture through finite element analysis. Nonlinear static analysis is carried out to analyse the design by using Solidworks. Design optimisation is also implemented to ensure the walkable chair is functional under a desired applied load. In this analysis, the 6061-T6 aluminium alloy was selected as the main material due to its high strength-to-weight ratio and excellent corrosion resistance. The result showed 61.54 MPa of maximum von Mises stress located at the joint support component after the walkable chair is subjected to 50 kg of applied load per extremity. While other components bear lesser von Mises stress compared to joint support. Based on the result, a 4.47 value factor of safety is calculated, and this indicated the structural design can sustain four times the maximum von Mises stress without fail.
