ABSTRACT
Scissor frame structures (SFS) have attracted significant attention due to their flexibility of deployment and stiffens once fully deployed. These features benefit prefabrication and transportation over traditional frame structures, with potential for modular structure implementation. However, current research often neglects structural analysis, focusing on geometrical and kinematic designs. This oversight, combined with critical load conditions at the locking mechanism linkage, risk underdesigning the SFS and leading to potential structural failure. This study conducted load testing on four SFS specimens with varying cross-sections and heights. Results were discussed based on the measured strain, displacement, and validation with FEM modelling. Analysis shows that despite the flexibility inherent in their pivotal points and multi-plane connections, the SFS exhibits linear behavior under external loads within the elastic range, with symmetrical results akin to single-plane action. Furthermore, three SFS FEM models, developed using SCIA Engineer software, were validated and revealed that loading on the locking mechanism linkage severely impacts structural efficiency. The capacities of the SFS specimens, calculated based on measured critical stress and stiffness, highlight the diverse effects of scissor depth and cross-section on SFS structural behaviour. This paper provides essential experimental data for SFS, assisting engineers in precise structural analysis and assessment.
