Abstract text:
In this article it is highlighted the evolution of the romanian seismic standards concerning reinforced concrete (RC) wall buildings. For the same type of building the values of the seismic forces against the seismic romanian standards are analysed. The first particular seismic design code in Romania was based mainly on the Soviet regulations at the time. It referred to a seismic zoning of Romania, that has been continously improving ever since and it layed out the formula to calculate the seismic forces for a specific building. The c global coefficient for reinforced concrete wall buildings has been evolving ever since towards its ultimate goal, that is to attain the real behaviour characteristics of the studied buildings. In present time this coefficient shows a significantly higher value than it did in the regulations before 1977 earthquake. At the end of the paper there will be drawn some conclusions about the tendency of seismic design codes to show the real behaviour of reinforced concrete wall buildings.
Key Words:
normalized response spectra; global coefficient.
