Seismic Actions on Buildings According to the National Regulations and Eurocode 8 for Bosnia and Herzegovina

The National Rulebook for Technical Standards for Construction of Buildings in Seismic Areas is still legally valid in Bosnia and Herzegovina including seismological maps for return periods of 50, 100, 200, 500, 1000 and 10000 years. Institute for Standardization of Bosnia and Herzegovina introduced BAS EN 1998-1:2017 (Eurocode 8) in national standardization, while National Annex BAS EN 1998-1/NA:2018 was introduced in 2018, including seismic hazard maps for Bosnia and Herzegovina with reference return periods of 475 and 95 years, as well as an interactive map showing values for reference PGA on type A ground for the same reference return periods. However, application of Eurocodes is not mandatory yet. In this research, comparison, and analysis of seismic forces according to the national Rulebook and Eurocode 8 for several cities in Bosnia and Herzegovina are conducted on the various building models, showing interesting results as a basis for possible further academic and experts discussions in approach to the structural design for seismic resistance in Bosnia and Herzegovina.
