We compute gravitational waves emitted by the collapse of a rotating very massive star (VMS) core leading directly to a black hole in axisymmetric numerical-relativity simulations. The evolved rotating VMS is derived by a stellar evolution calculation, and its initial mass and the final carbon-oxygen core mass areand, respectively. We find that, for the moderately rapidly rotating cases, the peak strain amplitude and the corresponding frequency of gravitational waves areandfor an event at the distance of. Such gravitational waves will be detectable only forby second-generation detectors, advanced LIGO, advanced VIRGO, and KAGRA, even if the designed sensitivity for these detectors is achieved. However, third-generation detectors will be able to detect such gravitational waves for an event up to. The detection of the gravitational-wave signal will provide a potential opportunity for verifying the presence of VMSs with massand their pair-unstable collapse in the Universe.
