To provide a vibration testing apparatus for a structure which performs a vibration test with high precision even for a large-scale, complex, and nonlinear numerical model section when performing a vibration test with combining a vibration test with vibration response numerical analysis for only a part of the structure.

The vibration testing apparatus for a structure comprises vibrating means 4 for vibrating a real object model 2, load measuring means 6 for measuring a load, and a computer 5 to which the numerically modeled numerical model section 3 is inputted. The computer 5 comprises means 13 for calculating displacement after a lapse of predetermined time from the time of measurement on the basis of a load value and an external force value, means 14 for creating a command signal with the displacement set as a target figure, and step control means 15 for controlling so that the processes by these means are periodically performed. The command displacement calculation means 13 uses the αOS method for the temporal integration for a vibration equation. The balancing equation in each temporal step is based on an increment from the previous temporal step.
