The damage observed during recent earthquakes demonstrated the high vulnerability of non-structural elements due to accelerations and displacements arising from the structure’s seismic response. Non-structural elements that do not incorporate any seismic design generally exhibit damage at low seismic intensities and can significantly affect the immediate functionality of buildings.

Abstract
The damage observed during recent earthquakes demonstrated the high vulnerability of non-structural elements due to accelerations and displacements arising from the structure’s seismic response. Non-structural elements that do not incorporate any seismic design generally exhibit damage at low seismic intensities and can significantly affect the immediate functionality of buildings. This issue is of paramount importance for strategic facilities, such as hospitals and schools that must remain operational in the post-earthquake emergency response. Nowadays some impediments still hinder the introduction of seismic design of non-structural elements into practice. The introduction of the Building Information Modelling (BIM) technology has significantly enhanced several aspects of the planning, design and construction processes along with numerous aspects of the project management. The capability of BIM to organize and export information to external software could greatly increase the feasibility of conducting comprehensive and automatic seismic design and risk assessment. The use of BIM could represent a new frontier in the seismic design of non-structural elements by increasing the reliability of the seismic design. In this study, the effectiveness of using Building Information Models for the seismic design of non-structural elements is demonstrated. A conceptual framework to perform the automatic seismic design of non-structural elements using information available in Building Information Models is presented. A simple Excel based tool has been developed in order to perform the automatic seismic design of sprinkler piping systems. The design tool extracts the piping layout from Building Information Models and performs automatically the seismic design of sway bracings according to the seismic provisions of the NFPA13 standard in the United States. The effectiveness of the proposed conceptual framework, as well as of the developed design tool, is investigated via an illustrative example.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
