1st Croatian Conference on Earthquake Engineering 1CroCEE 2021

With the development of the new technologies and the modern residential and industrial buildings typology the non-structural components and systems become major part of the total value in building construction. This damage may result in loss of functionality, economic loss due to damage and even life safety hazards. Since they are not amenable to traditional structural analysis, full-scale experimental testing is crucial to understand their behavior under earthquake.
In this paper, results of the experimental testing of non-structural elements including raised floors, ceilings and cleanroom systems, performed at the Dynamic Testing Laboratory in the Institute of Earthquake Engineering and Engineering Seismology - IZIIS, Skopje, Republic of North Macedonia will be presented. Seismic certification of this systems has been conducted according to AC-156 - Acceptance criteria for seismic qualification by shake table testing for non-structural components. For this reason, a steel cube structure was properly designed in order to simulate the seismic effects at a generic building story where different types and configurations of non-structural elements were implemented. Results have been obtained in terms of accelerations, displacements and strains in characteristic points. The systems showed good performance and it was confirmed that all acceptance criteria have been fulfilled during and after the seismic tests. Based on the experimental research it was observed that most of the tested non-structural elements successfully passed the seismic acceptance criteria for shake table testing of non-structural components and systems according to ICC AC-156.
