Required Response Spectra and Acceleration Loading Histories for Seismic Assessment of Acceleration-Sensitive Nonstructural Elements According to the Italian Building Code

The assessment of the seismic performance of nonstructural elements (NEs) is typically required by the current international codes, regulations, and guidelines. Required response spectra (RRS) and acceleration testing inputs are the key parameters for defining shake table testing protocols suitable for both assessment and qualification of acceleration-sensitive NEs. However, international codes and guidelines define RRS and acceleration time histories that are not necessarily consistent with seismic demands associated with Italian and European territories. In this study, novel RRS and acceleration time histories are developed for a consistent shake table assessment of acceleration-sensitive NEs according to the Italian building code. A critical review of existing protocols was carried out to define new approaches for developing code-consistent assessment and qualification protocols. The approach used to develop RRS and testing inputs is widely applicable and easily extendable to different case studies as the process is highly flexible and adaptable. The application of the developed methodology lays the foundations for the development of code-consistent shake table protocols for both assessment and qualification purposes.
