This paper investigates the seismic behavior of an electrical cabinet considering the influence ofequipment-anchor-interaction (EAI) that is generally not taken into consideration in a decoupled analysis. The hysteresis behavior of an anchor bolt in concrete was thereby considered to highlight thisinteraction effect. To this end, the experimental behavior of an anchor bolt under reversed cyclic loadingwas taken from the recently developed literature, and a numerical model for the anchor hysteresis wasdeveloped using the component approach. The hysteresis properties were then used to calibrate themulti-linear link element that is implemented as a boundary condition for the cabinet incorporating theEAI. To highlight this EAI further, the nonlinear time history analysis was performed for a cabinetconsidering the hysteresis behavior comparative to a fixed boundary condition. Additionally, the influence on the seismic fragility was evaluated for the operational and structural condition of the cabinet.
The numerical analysis considering the anchor hysteresis manifests that the in-cabinet response spectra(ICRS) are significantly amplified with the corresponding reduction in the seismic capacity of 25% and15% for an operational and structural safety condition under the selected protocols. Considering the fixedboundary condition over a realistic hysteresis behavior of the anchor bolt is more likely to overestimatethe seismic capacity of the cabinet in a seismic qualification procedure
