A new type of array combined formwork support system is composed of array aluminium frames, adjustable steel pipe supports, horizontal tubes and plastic templates. A single-span four-column frame unit was selected to perform a full-scale anti-overturning stability experiment on the formwork support system. The experiment results showed that the formwork support system remained stable and exhibited good lateral stiffness under horizontal load. It could meet the requirements of overall anti-overturning stability with the cooperation of beam and column formworks. On this basis, the finite element software MIDAS/Gen was used to establish a three-dimensional analysis model of the experiment frame structure considering the semi-rigidity of joints, and the geometric non-linear analysis was carried out. By comparison, the analysis results were generally consistent with the experimental data, which showed that the modeling and analysis methods in the paper were basically consistent with the actual stress state of the experiment frame structure. The inevitable or expected randomness of member quality, material defects, installation operation and connection construction had a certain effect on the overall stability of the formwork support system.
