Tada and Kuwahara proposed a scheme for Internet-based structural analysis in which many researchers worldwide can collaborate and unify their different programs and structural models. This paper first introduces the structural loading system of an exposed column-base. This loading system enables us to simulate the variation of rotational stiffness and bending moment carrying capacity under varying axial force. Hence, the technique of Internet-based structural analysis is used to perform the collaborated pseudo dynamic test on a building frame with an exposed column-base subjected to vertical and horizontal forces. The results show the simplicity of the collaboration producers, the stable transfer of information between programs and loading system, and the overall complicated resisting behavior of a canti-lever with semi-rigidly-connected column-bases.
