A Comparative Study of the Seismic Provisions between Iraqi Seismic Codes 2014 and 1997 for Kurdistan Region/Iraq
This paper addresses the effect of the seismic design response spectral acceleration parameters recommended by the Iraq Seismic code 2014 (ISC 2014) compared to that recommended by the previous Iraq Seismic code 1997 (ISC 1997) for the cities of Kurdistan Region of Iraq (Erbil, Duhok, Sulaymaniyah a...

| Summary: | This paper addresses the effect of the seismic design response spectral acceleration parameters recommended by the Iraq Seismic code 2014 (ISC 2014) compared to that recommended by the previous Iraq Seismic code 1997 (ISC 1997) for the cities of Kurdistan Region of Iraq (Erbil, Duhok, Sulaymaniyah and Halabja). The seismic design response spectral recommended by the ISC 2014 for these cities have been prepared for hard rock, rock, very stiff soil, stiff soil, and soft soil. Then, based on the equivalent lateral force procedure, the base shear calculated using both codes have been compared for two case studies of reinforced concrete building consists of 5 and 15 floors. The results showed that ISC 2014 provisions results in a dramatic increase in the base shear forces especially for the cities of Halabja and Sulaymaniyah, followed by Erbil city, while the effect on Duhok city was relatively low. As a supplementary work, modal response spectrum analysis has been performed using ISC 2014 on a 5 and 15 story regular reinforced concrete framed building constructed on soil type D-stiff soil and located in Erbil to evaluate the results of the equivalent lateral force procedure.based on ISC 2014 provisions, all the buildings in KRI should be assigned to the seismic risk class D, meaning that the building construction system should be either special reinforced concrete frame, special reinforced shear wall, special reinforced masonry wall, special steel frame, or ordinary/intermediate steel frame for specific frame configurations. |
