Abstract
The three-year project is concerned with the further development of the simplified nonlinear method (N2 method) for seismic performance evaluation of structures, and with its formulation in a form, which is appropriate for practical application. The method has been developed within the research group in Ljubljana and has been used worldwide. In 2002 the method has been implemented into the European standard Eurocode 8. The extensions of the method will include:
(a) Extension of the applicability to asymmetric building structures;
(b) Extension to allow seismic risk analysis;
(c) Determination of the capacity of structural elements of typical reinforced concrete building structures using the existing data bases;
(d) "Safety" factors, which will take into account the randomness and uncertainties of the problem, will be proposed. They will be based on results obtained by statistical methods and probabilistic approach. The final aim of research is development of a relatively simple and reliable methodology for seismic performance assessment, which could be applied in practice for design of new structures and for the assessment of existing structures.
Comprehensive research work will include the development of the theoretical basis, parametric studies of nonlinear dynamic response of typical structures, improvement of a non-parametric multidimensional regression method and its application for the analysis of the existing data bases of experimental results, and validation of the N2 method by comparison with experimental results. The work can be successfully performed only in close cooperation with the leading research centers for earthquake engineering worldwide. The group in Ljubljana has informal contacts with the majority of such centers. Formal cooperation (joint projects) has been established with 47 institutions in Europe (SPEAR and LESSLOSS projects), and with the leading center the U.S.A. (Stanford University). The work in Ljubljana is limited to analytical and numerical research. The results of complex and extremely expensive experiments will be obtained from foreign research centers. Some experiments will be performed with the active participation of the researchers from Ljubljana.
The proposed project is closely related to and fully coordinated with the work of the research group working in Earthquake engineering at the Faculty of Civil and Geodetic Engineering. Independent researcher I.Peruš has been working within the group in the past, however, for formal reasons, he cannot be formally included in the group.
