Seismic hazard zoning in Urmia urban area.
Today, the resiliency of the human centers, especially urban centers against the natural hazards such as earthquakes, is one of the main challenges in the targeted management of urban. One of the effective strategies in the control, containment and prevention of risks from earthquakes is zoning of urban areas in terms of vulnerability. In this regard, the purpose of this study was to determine...
متن کاملseismic zoning of tehran region using fuzzy sets
seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to variety of parameters affecting the occurrence of earthquake. uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rationale way. herein, fuzzy set theory is used to take into account the uncertainty existed in the seismic hazard analysis. the...
متن کاملA fast partitioning algorithm using adaptive Mahalanobis clustering with application to seismic zoning
In this paper we construct an efficient adaptive Mahalanobis k-means algorithm. In addition, we propose a new efficient algorithm to search for a globally optimal partition obtained by using the adoptive Mahalanobis distance-like function. The algorithm is a generalization of the previously proposed incremental algorithm [36]. It successively finds optimal partitions with k = 2, 3, . . . cluste...
متن کاملDesign Philosophy for Steel Structures in Moderate Seismic Regions
The authors propose a design philosophy for steel buildings in moderate seismic regions that draws on familiar concepts of ductility and capacity design, but also integrates the concepts of reserve capacity, elastic flexibility and strength to broaden the field of design possibilities. The paper discusses structural systems representing each of these concepts: Moderate-Ductility Concentrically-...
متن کاملRecent 2017-2018 Seismicity and News Seismic Hazard Zoning of Iran
On November 12, 2017, at 18:18 UTC, a major earthquake with moment magnitude Mw7.3 struck the Kermanshah province of Iran, causing extended damage and casualties. Thus, we explore seismicity preceding this earthquake, with the aim to understand whether the information from past events could provide some insights about the occurrence of this and other future large earthquakes. Taking into accou...
