Methodology to characterize and quantify debris generation in residential buildings after seismic events

摘要: Abstract Earthquakes are natural phenomena that can cause severe damage to housing infrastructure and prolonged disruption society. Depending on their magnitude, epicenter location, local construction characteristics, many other features, earthquakes may generate large amounts of debris waste. The generated after the disaster become one main problems for a population facing health issues need reconstruct city. Proper characterization quantification debris, subsequent waste management reconstruction planning essential restoration an area affected by earthquake. This study presents methodological approach characterize, quantify forecast produced as consequence earthquakes, well flow materials required affected. proposed methodology includes residential stage, probabilistic estimation characterizing vulnerability functions using CAPRA-GIS tool, material analyses (MFA) associated with event earthquake new stage. A case was developed test this approach. sector Tacna, city high seismic risk located southern coast Peru, selected. Moreover, five different systems (i.e., reinforced masonry-bearing walls concrete diaphragms, adobe, wood, shear walls, straw) used in Tacna were characterized. Also, three possible scenarios 8.6 M w , 7.5 M 6.2 M ) analyzed, each end-of-life situations. Simultaneously, origin quantities needed determined. considered productivity rates manufacturing sectors. results show presence greatest (8.6 M ), adobe straw homes suffered damage, proportions 63% 48%, yielding 27,000 1390 tonnes respectively. 204,000 tonnes concrete, 7400 tonnes steel 461,400 tonnes clay brick included scenario. Furthermore, all scenarios, MFA provides estimate regional import (e.g., cement, steel, wood) phase. Finally, is applicable undeveloped countries types, respective constant recurrence.
