The article presents the investigation of the seismic behaviour of a modern URM building located in the municipality of Finale Emilia in province of Modena, Northern Italy. The building is situated in the centre of the series of the 2012 Northern Italy earthquakes and has not suffered any damage during the earthquake series in 2012. The observed earthquake resistance of the building is compared with predicted resistances based on linear and nonlinear design approaches according to Eurocode. Furthermore, probabilistic analyses based on nonlinear calculation models taking into account scattering of the most relevant input parameters are carried out to identify their influence to the results and to derive fragility curves.

Silos generally work as storage structures between supply and demand for various goods, and their structural safety has long been of interest to the civil engineering profession. This is especially true for dynamically loaded silos, e.g., in case of seismic excitation. Particularly thin-walled cylindrical silos are highly vulnerable to seismic induced pressures, which can cause critical buckling phenomena of the silo shell. The analysis of silos can be carried out in two different ways. In the first, the seismic loading is modeled through statically equivalent loads acting on the shell. Alternatively, a time history analysis might be carried out, in which nonlinear phenomena due to the filling as well as the interaction between the shell and the granular material are taken into account. The paper presents a comparison of these approaches. The model used for the nonlinear time history analysis considers the granular material by means of the intergranular strain approach for hypoplasticity theory. The interaction effects between the granular material and the shell is represented by contact elements. Additionally, soil–structure interaction effects are taken into account.

Seismic safety verification can be performed by maintaining constructive rules or by calculation. Verification by calculation can be performed with a linear simplified or linear multi-modal response spectrum analysis. Alternatively, a non-linear quasi-static verification is also possible according to DIN EN 1998-1, which was not available in DIN 4149. In this article, the non-linear quasi-static earthquake verification according to DIN EN 1998-1 is presented in practice, using the example of a building in Mittenwald/Germany. The verification has been checked and accepted by an independent building supervision report. Der Nachweis der Erdbebensicherheit kann durch die Einhaltung von konstruktiven Regeln oder einen rechnerischen Nachweis erfolgen. Der rechnerische Nachweis kann linear mit dem vereinfachten oder multimodalen Antwortspektrenverfahren erfolgen. Alternativ ist nach DIN EN 1998-1 ein nichtlinearer quasi-statischer Nachweis möglich, der in der DIN 4149 noch nicht zur Verfügung stand. Im Rahmen dieses Beitrags wird der nichtlineare quasi-statische Erdbebennachweis nach DIN EN 1998-1 anhand eines konkreten Bauobjektes in Mittenwald vorgestellt. Der Nachweis wurde durch eine unabhängige bauaufsichtliche Begutachtung überprüft und akzeptiert.
