In this paper, influence of in-plane vibration on building SEA model for flexural vibration on beam-like structures with an arbitrary angle is investigated. We develop the assessment method of the influence of in-plane vibration on the built SEA model for the flexural vibrations on the L-shaped plates. The method is useful to identify the frequency bands affected by the in-plane vibration and how the coupling loss factors are under- or over-estimated. The influence of in-plane vibration on beam structure is a simple compared to the ones of plate structure. A proposed method as mentioned above is effective for the structures composed of two beams connected in an arbitrary angle.
