Seismic resistance qualification is mandatory for telecommunication equipment prior to network deployment. While sinusoidal resonance beat waves (SRBWs) serve as optional excitations in seismic testing, practical applications have revealed operational limitations. This study comparatively investigated the seismic responses of typical telecommunication cabinets through shaking table tests using both SRBWs and artificial ground motions (AGMs). A comprehensive analysis of damage patterns, natural frequencies, deformations, and acceleration responses demonstrated SRBWs’ superior efficacy in exciting seismic reactions for equipment with natural frequencies exceeding 3 Hz. The findings substantiate the necessity of employing SRBW excitations for such equipment and the critical infrastructure categorized as “essential” or “important”. Furthermore, critical examination of the current Specifications for Seismic Test of Telecommunication Equipment (YD 5083—2005) reveals technical inconsistencies in SRBW implementation, prompting proposed revisions to enhance testing protocol reliability.
