20.500.12556/RUL-151785 Bias in the estimation of seismic risk for municipal building stocks due to limited data This study investigated the effect of the building data knowledge level on seismic risk estimation for municipal building stocks, focusing on identifying the characteristics that influence loss estimation bias. Fifteen municipalities in two Slovenian regions were analysed using twelve building data knowledge levels, defined by combining different knowledge levels about building location and floor area. The knowledge levels ranged from those using data aggregated at the municipality level to those using building-specific data. The bias was quantified as the log residual between the expected annual losses estimated for the given knowledge level and the base-case level, characterised by building-specific data. The results indicate that loss estimation bias is affected by both the building location and floor-area knowledge levels. The data on building density distribution across the municipality and building-class-specific floor areas are sufficient for estimating loss with low bias with respect to the base-case level. The effect of potential data improvement on bias reduction can be assessed using building stock homogeneity and hazard variation indexes determined from readily available data. Further research is needed to explore loss estimation bias for building data knowledge levels not considered in this study and generalise the concepts to other regions and building classifications. seismic risk loss estimation bias building data knowledge level municipal building stock limited data earthquakes potresno tveganje ocena izgub nivo poznavanja podatkov o stavbah občinski stavbni fond omejeni podatki true false true Angleški jezik Slovenski jezik Članek v reviji 2023-10-20 08:36:05 2023-10-20 08:36:08 2023-10-21 03:45:43 0000-00-00 00:00:00 2023 0 0 21 str. iss. 9, art. 2245 Vol. 13 2023 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.042.7 2075-5309 10.3390/buildings13092245 164050179 buildings-13-02245-v2_(1).pdf buildings-13-02245-v2_(1).pdf 1 F2C16C5E3B8B56438F07CA93B469FA87 bee91d56bfe42c36776cff3950c0ff89be4066a6fa4f1c79d57c672cf92088e7 378086c1-6f13-11ee-b452-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176848 https://www.mdpi.com/2075-5309/13/9/2245 1 f42fad68-6f12-11ee-b452-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176847 Fakulteta za gradbeništvo in geodezijo 0 0 0
