Abstract

ABSTRACT On 12th November 2017, an earthquake with a magnitude of 7.3 Richter scale in the town of Sarpol-e Zahab took place that caused lots of human casualties and devastation. After the incident, issues related to the probability of an earthquake with equal intensity and extents of similar building destruction were raised in Kermanshah city. Therefore, a seismic microzonation map of Kermanshah city has been prepared based on the geotechnical, geological, and geophysical data, and the data were analysed using Fuzzy analytic hierarchy process (AHP). In the next step, the vulnerability analysis of city buildings was carried out based on the ground-shaking map, vulnerability curves, and statistical data regarding the buildings. The results of the vulnerability rate of residential buildings indicate that 80% of residential buildings would be exposed to vulnerability from low to moderate. However, other buildings would suffer 2% fully destruction (D1), 7% very high destruction (D2) and 11% high destruction (D3), respectively. Finally, according to the obtained results, the proposed model is verified with the help of the data and observations from the Sarpol-e Zahab earthquake, which reveals that the model is in good agreement with the actual earthquake data.

基于场地特征和岩土参数的地震微区划及建筑易损评价——以克尔曼沙赫市为例

2017年11月12日，萨波尔扎哈布镇发生里氏7.3级地震，造成大量人员伤亡和破坏。事件发生后，在克尔曼沙阿市提出了与同样强度和程度的地震的可能性有关的问题。为此，在岩土、地质和地球物理资料的基础上，编制了克尔曼沙赫市地震微区划图，并采用模糊层次分析法(AHP)对数据进行分析。下一步，根据城市建筑物的地震图、易损性曲线和统计数据，对城市建筑物进行易损性分析。住宅易损率结果表明，80%的住宅易损率为低至中等。然而，其他建筑将分别遭受2%的完全破坏(D1)， 7%的高度破坏(D2)和11%的高度破坏(D3)。最后，根据所得结果，利用Sarpol-e Zahab地震资料和观测资料对模型进行了验证，表明模型与实际地震资料吻合较好。

期刊介绍： Civil Engineering and Environmental Systems is devoted to the advancement of systems thinking and systems techniques throughout systems engineering, environmental engineering decision-making, and engineering management. We do this by publishing the practical applications and developments of "hard" and "soft" systems techniques and thinking. Submissions that allow for better analysis of civil engineering and environmental systems might look at: -Civil Engineering optimization -Risk assessment in engineering -Civil engineering decision analysis -System identification in engineering -Civil engineering numerical simulation -Uncertainty modelling in engineering -Qualitative modelling of complex engineering systems
