Description

Engineered Urban type URM - 5 storeys Turkey Sample Data. Generic buildings developed for 120 $Paragraph$different sub-classes of URM by considering two $Paragraph$different existing building databases: $Paragraph$1) Dinar (Afyon) Turkey database, including $Paragraph$rural-type URM buildings damaged after the 1995 Dinar $Paragraph$earthquake.$Paragraph$2) Zeytinburnu (Istanbul) Turkey database, $Paragraph$including urban-type URM buildings examined in the $Paragraph$course of the Istanbul Earthquake Masterplan Project.$Paragraph$Seismic Hazard: Fifty ground motion records with stiff $Paragraph$site characteristics are selected with PGA values that $Paragraph$range between 0.01g and 0.8g.$Paragraph$$Paragraph$Uncertainties are quantified by the ß parameters. $Paragraph$Variability in base shear capacity (ßC) is obtained $Paragraph$through pushover analyses whereas variability in $Paragraph$demand (ßD) is established by employing time-history $Paragraph$analyses. Uncertainty introduced by structural modeling $Paragraph$(ßM) is assumed to be 0.3.$Paragraph$The fragility curve sets shown above have been $Paragraph$selected through 120 variants of fragility curve sets $Paragraph$generated for Turkish masonry buildings in terms of the $Paragraph$following major structural parameters: number of $Paragraph$stories, plan geometry, material quality and strength, $Paragraph$considerations on wall length and openings in walls. $Paragraph$These parameters have been selected by considering $Paragraph$two different masonry building databases from Dinar $Paragraph$(Afyon) and Zeytinburnu (Istanbul). $Paragraph$Since the number of stories has been observed to be a $Paragraph$very effective parameter on the seismic performance of $Paragraph$Turkish URM buildings, a fragility curve set is generated $Paragraph$for 1,2,3,4 and 5 story buildings individually instead of $Paragraph$considering as low-rise or mid-rise. In fact, the maximum $Paragraph$number of stories for URM buildings is also limited by the $Paragraph$current Turkish Earthquake Code (TEC-07).$Paragraph$The generated fragility curves are based on the in-$Paragraph$plane shear response of the most critical story of the $Paragraph$building, i.e. ground story for Turkish URM.$Paragraph$From the generated sets of fragility curves, it is $Paragraph$observed that the damage state probabilities are $Paragraph$significantly influenced from the number of stories and $Paragraph$wall material strength. Regularity in plan, length, and $Paragraph$arrangement of bearing walls in plan also have $Paragraph$significant effect on the damage state probabilities to $Paragraph$some extent. This shows that the inherent $Paragraph$characteristics of Turkish masonry buildings have been $Paragraph$well reflected in the generated set of fragility curves.$Paragraph$The damage estimated by using the fragility curve sets $Paragraph$was compared with the actual damage after Dinar $Paragraph$(1995) earthquake as assessed from the Damage $Paragraph$Evaluation Form and fair agreement between two $Paragraph$damage measures was obtained (Erberik 2008).
