In this paper, the experiments were performed to investigate the effect of position of the opening on the mechanical behaviors of the free-formed shells. And the effect of the opening under the different loading modes was also investigated. The reversed catenary surface was adopted as the shape of the free-formed shell. Three types of the model with openings at different position, including without opening, were tested under two loading modes and the results were compared each other. The results indicate that the position of openings affects not only the ultimate load and the stiffness, but also the mode of displacement and the stress flow. Especially, in case of the openings on the diagonal line, the deflection is amplified by the central partial loading. So, such situation should be avoided in the design of the reversed catenary shell.
