Special Issue Information

Dear Colleagues,

We are inviting submissions to this Special Issue dedicated to seismic zonation in the next-generation design codes.

In the light of the next-generation Eurocode 8, the seismic zonation maps at national level will be updated. The impact of such changes on new buildings and structures has to be evaluated from the point of view of structural safety. Among the most important changes in next-generation design codes is the definition of site conditions, an aspect which needs further research. Another critical aspect is related to the impact of the uniform risk versus uniform hazard approach. Moreover, other aspects related to the design response spectra, vertical ground motion, or assessment of seismic hazard uncertainty are also important aspects which have to be analyzed.

The aim of this Special Issue is to collect and disseminate the latest research in these fields from world-leading researchers. Contributions related to seismic hazard assessment, evaluation of site conditions, uniform hazard, and risk data from recent earthquakes in Europe are most welcome.

Preliminary Evaluation of the Impact of Eurocode 8 Draft Revision on the Seismic Zonation of Romania

by Florin Pavel, Radu Vacareanu and Kyriazis Pitilakis

Appl. Sci. 2022, 12(2), 649; https://0-doi-org.brum.beds.ac.uk/10.3390/app12020649 - 10 Jan 2022

Abstract

This study is focused on the impact of the Eurocode 8 draft revision on the seismic zonation of Romania, one of the countries with the highest hazard levels in Europe. In this study, the design response spectra are evaluated for a number of sites in Romania for which both shear wave velocity profiles and ground motion recordings are available. The impact of the proposed changes on the structural design for structures situated in the southern part of Romania is also discussed. The results show considerable differences between the design response spectra computed according to the Eurocode 8 draft revision and the design response spectra from the current Romanian seismic code P100-1/2013. The differences are larger in the case of the sites situated in the southern part of Romania and those which have large design values for the control period T_C. In Bucharest, for instance, it was found that the maximum design spectral accelerations would correspond to those from the 2006 version of the code while the maximum design spectral displacements would be significantly smaller than the levels produced by the 1981 or 1992 versions of the code. The results presented herein show that the differences in the seismic hazard and design ground motions are mainly due to the effects of local soil and site conditions and the associated site amplification proposed in the current Romanian seismic code and EC8 draft revision. Moreover, it has been shown that more analyses are needed to apply the seismic actions proposed in Eurocode 8 revision specifically for the sites in Romania under the influence of Vrancea intermediate-depth earthquakes so as to ensure an increased level of seismic safety for structures designed and built in the future.

An Overview of the Seismic Elastic Response Spectra and Their Application According to Mexican, U.S., and International Building Codes

by Arturo Gonzalez and Julio Calderon

Appl. Sci. 2022, 12(7), 3472; https://0-doi-org.brum.beds.ac.uk/10.3390/app12073472 - 29 Mar 2022

Abstract

The design of earthquake-resistant structures by applying traditional or performance-based seismic analysis methods involves two large variables: the seismic risk of the area and the physical characteristics of the structure. Before analyzing any building, it is required to determine the seismicity in the location to evaluate the accelerations that the structure must withstand by deterministic or probabilistic methods. The typical results of a seismic study are the uniform hazard spectra in the rock layer related to a specific return period and structural damping. The building codes use different methods to obtain the elastic response spectra, seeking to offer simple procedures by using parametric factors to consider the soil type; however, the procedure tends to return conservative estimates. On the other hand, site-specific spectra offer accurate and less conservative acceleration values, with the disadvantage of an extensive and costly mathematical process, justifying their application mostly to important structures. This review article gives the state of the art of seismic elastic response spectra using probabilistic seismic hazard maps as inputs, taking into account the importance of the structure and the soil type, according to Mexican, U.S., and international building codes.
