European Seismic Design Practices for Building Structures

In order to develop and enhance our methodology of seismic design in the next generation thee is a need to analyze the environment chronicles and concept of the seismic design in foreign countries. For this purpose we have researched the cases of U.S.A and Europe. In this paper the emphasis was put on the european seismicity and seismic design practices for building structures. In this study the comparison of seismic design codes in some european countries regarding fundamental period and design base shears leads to the conclusion that there exists remarkable difference in the approaches. Particularly the base shears used in european countries give larger values than the one proposed by UBC 97. Though each european country has established similar seismic design code there are also still large difference in the level of construction technology and societal implementation of seismic codes.
