Abstract
The proposed two-year project is concerned with the development of a practice-oriented method for seismic risk analysis of buildings. To achieve this aim, the simplified non-linear (N2) method, developed at the University of Ljubljana and implemented in 2002 into Eurocode 8, will be extended. The theoretical background and the basic ideas of the probabilistic methodology, developed at the Stanford University, that de-composes the problem into three basic elements of seismic hazard analysis, seismic demand prediction and failure or loss estimation, will be employed. A further extension of the N2 method will allow the analysis of infilled reinforced concrete (RC) frame structures. The method will be applied for analysis of typical test examples of RC frames without and with infill. The mathematical models will be evaluated by comparisons with the results of full-scale tests performed in Ispra. For investigated structural types partial safety factors will be proposed, which will be based on statistical treatment of randomness and uncertainty. Comprehensive research work will include the development of the theoretical basis, parametric studies of nonlinear dynamic response of typical structures, and evaluation of mathematical models. 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 15 institutions in Europe (projects SAFERR and SPEAR). The bilateral joint project with Stanford University will be formally concluded by the end of 2002, but the cooperation will continue. The work in Ljubljana will be 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. Within the proposed "post-doc" project, supervised by P.Fajfar, M.Dolšek will continue research performed within his Ph.D.thesis.
