“…There are studies on estimating physical and social seismic vulnerabilities in urban areas in the literature ([e.g., References [3][4][5][6][7][8][9]). Some of the studies in the literature use existing analytical relations or vulnerability indices in a spatial decision support system (SDSS) framework where the pre-defined vulnerability codes for buildings are available for estimating buildings' damages ([e.g., References [8,[10][11][12][13][14][15][16][17]). However, a few studies have considered estimating building damage as a decision making problem concerning the necessity of PSVA in earthquake prone areas that lack required data for defining mathematical vulnerability relations/ indices (the mentioned data include details of structural properties of existing buildings and/or the statistical data of building damage from previous earthquakes) [18][19][20][21].…”

Earthquake is one of the natural disasters which threaten many lives every year. It is impossible to prevent earthquakes from occurring; however, it is possible to predict the building damage, human and property losses in advance to mitigate the adverse effects of the catastrophe. Seismic vulnerability assessment is a complex uncertain spatial decision making problem due to intrinsic uncertainties such as lack of complete data, vagueness in experts’ comments and uncertainties in the numerical data/relations. It is important to identify and model the incorporated uncertainties of seismic vulnerability assessment in order to obtain realistic predictions. Fuzzy sets theory can model the vagueness in weights of the selected criteria and relationships of the criteria with building damage. Dempster’s combination rule is useful for fusion of information on the vulnerability of the buildings which leads to decreased uncertainty of the results. However, when there is a conflict among information sources, classical Dempster rule of combination is not efficient. This paper analyses the uncertainty sources in a geospatial information system (GIS)-based seismic vulnerability assessment of buildings and then focuses on assessing the efficiency of Dempster rule of combination in the fusion of the information sources for the seismic vulnerability assessment. Tabriz, a historical and earthquake prone city in the north west of Iran was selected as the study area. The results verified that some inconsistencies among information sources exist which are important to be considered while proposing a method for the fusion of the information in order to obtain vulnerability assessments with less uncertainty. Based on the assessed building damage, the number of probable victims was estimated. The produced physical and social seismic vulnerability maps provide the required information for urban planners and administrators to reduce property and human losses through pre-earthquake mitigation and preparedness plans efficiently.

Irregularity of the Distribution of Masonry Infill Panels and Its Effect on the Seismic Collapse of Reinforced Concrete Buildings

et al. 2021

On 16 April 2016, an earthquake of Mw 7.8 shook the coast of Ecuador, causing the destruction of buildings and a significant number of casualties. Following a visit by the authors to the city of Portoviejo during the debris removal and recovery stage, it was noted that several reinforced concrete buildings located on corners had collapsed in the central part of the city. These buildings were characterized by the presence of masonry at the edges of the buildings but not between the two mostly open-plan facades on the corner for practical reasons. This article reviews the effect of masonry infill panels on the seismic response of reinforced concrete structures. For this, a model that contains the geometric and mechanical characteristics typical of collapsed buildings was generated and subjected to nonlinear analysis, with both static and dynamic increments. The results show the clear influence of the masonry infill panels on the structural response through the torsional behavior that is reflected in the evolution of the floor rotations. Finally, dynamic incremental analysis is used to obtain the collapse fragility curve of the building, and a new damage measure based on floor rotations is proposed.

La vivienda de adobe es una de las tipologías constructivas más representativas de la arquitectura tradicional y de la cultura local en México. En las últimas décadas estos sistemas han sufrido un abandono y desplazamiento por materiales y técnicas contemporáneos, situación que no ha hecho más que acrecentarse tras los recientes eventos sísmicos ocurridos en el país, especialmente los del año 2017. La localidad de Jojutla, en el estado de Morelos, fue una de las más afectadas por el sismo de Puebla de 2017, sufriendo daños irreparables en su patrimonio edificado, donde destaca la pérdida de las viviendas de ado- be del centro histórico. Con la presente investigación se hizo un estudio completo en la localidad señalada y la afectación sísmica en las construcciones de adobe tras los eventos de 2017. Para ello se empleó una metodología que incluyó análisis mediante sistemas de información geográ ca, caracterización de los materiales constructivos de tierra en el laboratorio, y la revisión de las regulaciones constructivas y los planes de gestión de riesgos del municipio. Pudieron observarse graves de ciencias constructivas en las viviendas, así como una incorrecta planificación a nivel urbano y de gestión de riesgos en la localidad, lo que contribuyó a aumentar la vulnerabilidad sísmica de las edificaciones. A partir de las investigaciones previas y de los resultados que se presentan, pudo establecerse que las viviendas de adobe fueron desprotegidas por las autoridades, aunado al olvido de los sistemas tradicionales y las malas prácticas, lo cual derivó en la desaparición de esta cultura constructiva en la región estudiada.
