Seismic resilience of internet data center building with different disaster mitigation techniques
Internet data center buildings have great importance for maintaining the post-earthquake functionality of telecommunication networks. It is essential to maintain the functionality of internet data center buildings during earthquakes or recover immediately after earthquakes, which is referred to as seismic resilience. In this study, a seismic resilience assessment framework based on the Chinese code GB/T 38591-2020 is introduced first. The seismic damage and post-earthquake repair of both structural components and non-structural components are considered in the resilience assessment framework. A method for post-earthquake functionality loss quantification is proposed based on damage state and functionality loss of component. The subsystem level and system level functionality loss can be obtained by an integration principle. The seismic resilience of a typical internet data center building was evaluated to demonstrate the effectiveness of the proposed method. To enhance the seismic resilience level, different disaster mitigation techniques including the energy dissipation technology using buckling restrained braces and the base-isolation technology using lead-rubber bearings are adopted. The seismic resilience is quantified and the corresponding seismic resilience curves under different earthquake intensities are developed based on evaluation results.
