Abstract
Metoda za procjenu seizmičkog ponašanja srednje visokih AB građevina
Highlights
Earthquakes registered over the last 50 years, such as Lice/Diyarbakır-Turkey (1975) of 6.6 magnitude, SpitakArmenia (1988) of 7.0 magnitude, Marmara-Turkey (1999) of 7.4 magnitude, Gujarat-India (2001) of 7.9 magnitude, Sumatra-Indonesia (2004) of 9.1 magnitude, KashmirPakistan (2005) of 7.6 magnitude, Sichuan-China (2008) of 7.9 magnitude, Haiti (2010) of 7.0 magnitude, TohokuJapan (2011) of magnitude 9.0, Erciş/Van-Turkey (2011) of 7.2 magnitude, Pakistan (2013) of 7.8 magnitude, and Iran-Iraq (2017) of 7.3 magnitude, clearly show that many buildings situated in seismic regions all around the world, in less developed or underdeveloped countries, are vulnerable to earthquake action
A simplified version of the performance based rapid seismic assessment method (PERA) method for rapid evaluation of seismic safety of the existing medium-rise reinforced concrete frame structures is proposed in the paper
The analysis steps of the PERA procedure were used by replacing the Muto method with the Smith method
Summary
Earthquakes registered over the last 50 years, such as Lice/Diyarbakır-Turkey (1975) of 6.6 magnitude, SpitakArmenia (1988) of 7.0 magnitude, Marmara-Turkey (1999) of 7.4 magnitude, Gujarat-India (2001) of 7.9 magnitude, Sumatra-Indonesia (2004) of 9.1 magnitude, KashmirPakistan (2005) of 7.6 magnitude, Sichuan-China (2008) of 7.9 magnitude, Haiti (2010) of 7.0 magnitude, TohokuJapan (2011) of magnitude 9.0, Erciş/Van-Turkey (2011) of 7.2 magnitude, Pakistan (2013) of 7.8 magnitude, and Iran-Iraq (2017) of 7.3 magnitude, clearly show that many buildings situated in seismic regions all around the world, in less developed or underdeveloped countries, are vulnerable to earthquake action. The earthquake resistance of our existing buildings can not be determined quickly according to the principles of Turkish Seismic Code (TSC 2007 [1]) and Regulation on the Determination of Risky Structures (RDRS) [2] For this reason, with the introduction of the urban regeneration process in Turkey, it has become necessary to use simpler, faster but still reliable methods. The first vibration mode of earthquake effect is proposed for dominant reinforced concrete frame structures This method is based on the member tributary area concept and includes various simplifications and assumptions related to the structural analysis and performance-based evaluation. Since the seismic safety assessment is based on TSC 2007 [1], potential problems such as non-compliance with the code of conduct, likely to occur if other quick evaluation methods are used, are reduced to minimum [33]
