Seismic performance

An evaluation of the confinement functions in the HCF must consider the state of the confinement structures, and the potential flow and/or leakage paths that would result in dose consequences to either on-site or off-site personnel. Two outside evaluations of the seismic performance of HCF SSCs form the basis for this DBE analysis. The first, performed by Walla Engineering Ltd in December 1998, was an evaluation of the east shield wall of Zone 2A. This wall has the greatest potential for failure in a seismic event of ail of the basement concrete structural elements, since it is unrestrained at the top. The second evaluation is a qualitative assessment of several SSCs performed by Chavez-Grieves based on an on-sHe inspection, reported in memorandum format dated May 18,1999.

Since RC buildings are very common both in Turkey and around the world, a number of previous studies have focused on their seismic performance assessment. Several rapid or preliminary assessment procedures have been proposed FEMA 154 (2002), Japanese Seismic Index (Kaminosono 2002), DURTES (Temiir 2006), P25 (Bal et al. 2007), Sextos et al. (2008), Ilki et al. (2003), Yakut (2004). Among these, FEMA 154 is a rapid assessment procedure that has been developed for US buildings, thus reflects practice there. Other procedures require more detailed data than those used in the proposed methodology. 

The scores assigned to the parameters used in the performance assessment procedure explained above are based on observations from past earthquakes and then-relative influence on structural performance. Accuracy and validity of these scores are assessed using two databases 1. Building damage database compiled after the 1999 Duzce earthquake 2. Buildings whose seismic performance was assessed using detailed procedures. 

The objective of the second phase of this study was to investigate the seismic performance of MRM infill walls under low and moderate hazard levels. Therefore,... 

The results show that the PTMS strengthening improved significantly the seismic performance of the deficient damaged building. For the same intensity at PGA = 0.15g, the repair and PTMS strengthening reduced the interstory drift...

The experimental tests clearly pointed out the potential of the recommended FRP solution to increase the seismic performances of beam-column joints designed according to non-seismic code provisions. The experimental validation of this local strengthening technique may strongly encourage the use of local interventions based on the use of FRP reinforcement to significantly increase both the local and global seismic capacity of RC structures.
