Abstract:The main purpose of this study is to develop a Geospatial Information System (GIS) model with the ability to assess the seismic damage to pipelines for two well-known hazards, including ground shaking and ground failure simultaneously. The model that is developed and used in this study includes four main parts of database implementation, seismic hazard analysis, vulnerability assessment and seismic damage assessment to determine the pipeline's damage probability. This model was implemented for main water distribution pipelines of Iran and tested for two different earthquake scenarios. The final damage probability of pipelines was estimated to be about 74% for water distribution pipelines of Mashhad including 40% and 34% for leak and break, respectively. In the next step, the impact of each earthquake input parameter on this model was extracted, and each of the three parameters had a huge impact on changing the results of pipelines' damage probability. Finally, the dependency of the model in liquefaction susceptibility, landslide susceptibility, vulnerability functions and segment length was checked out and specified that the model is sensitive just to liquefaction susceptibility and vulnerability functions.

“…Iran's regulation for seismic design of buildings [14] classi es sites into four categories based on average shear velocity measured up to the depth of 30 m (V 30 ). In order to make the proposed relations consistent with Iran's national regulations for seismic design of buildings [14], conditions of sites are categorized based on average shear velocity measured up to the depth of 30 m [15][16][17][18], which is used according to Table 1 ( Figure 3(b)). …”

Ground Motion Prediction Equation for Inelastic Spectral Displacement in Iran

et al. 2017

Abstract. This paper is devoted to investigating the inelastic displacement spectra compatible with Iran. Owing to inadequacy of code-compliant elastic design spectra to predict structural damage during sever earthquakes, di erent approaches are proposed to overcome this problem. Inelastic design spectrum is one of the most well-known methods introduced by researchers. In practice, attenuation relationships can be used in probabilistic seismic hazard analysis to obtain the inelastic design spectrum. In this paper, a new Ground Motion Prediction Equation (GMPE) has been proposed for inelastic spectral displacement. In this regard, 806 horizontal ground motions are utilized with magnitudes ranging from 4 to 7 and epicentral distances less than 200 Km, which are obtained from 330 earthquakes in Iran. According to the tectonic condition, Iran zone can be divided into two parts: Zagros and Alborz-central Iran. However, three equations have been presented for the whole country zone, Zagros and Alborz-central Iran zones, separately. The main parameters such as earthquake magnitude, site-source distance, and site conditions have been related to the inelastic spectral displacement. Based on average shear wave velocity to a depth of 30 m, sites have been categorized into three classes. For the purpose of practicality, simpli ed equations have been proposed to predict inelastic spectral displacements in Iran.

“…Site conditions were also evaluated from spectral ratios between horizontal and vertical components of earthquake recordings (e.g. , Lermo & Chávez -García, 1993;Field & Jacob, 1995;Atakan, 1995;Zaré et al, 1999;Rodriguez & Midorikawa, 2003;Zhao et al , 2006;Haghshenas et al, 2008) and from normalised spectral shapes (SA/PGA). Additiona lly, site conditions were evaluated from down-hole arrays as well as from soil-to-rock spectral ratios for sites sufficiently close to one another.…”

Subduction earthquakes along the Pacific Coast of Central America generate considerable seismic risk in the region. The quantification of the hazard due to these events requires the development of appropriate ground -motion prediction equations , for which purpose a database of recordings from subduction events in the region is indispensable. This paper describes the compilation of a comprehensive database of strong ground-motion recordings obtained during subduction-zone events in Central America , focusing on the region from 8 to 14ºN and 83 to 92ºW, i ncluding Guatemala, El Salvador, Nicaragua and Costa Rica. More than 400 accelerograms recorded by the networks operators across Central America during the last decades have been added to data collected by NORSAR in two regional projects for the reduction of natural disasters. The final database consists of 554 triaxial ground-motion recordings from events of moment magnitudes between 5.0 and 7.7, including 22 interface and 58 intraslab-type events for the time period . Although the database presen ted in this study is not sufficiently complete in terms of magnitude-distance distribution to serve as a basis for the derivation of predictive equations for interface and intraslab events in Central America, it considerably expands the Central American subduction data compiled in previous studies and used in early ground-motion modelling studies for subduction events in this region. Additionally, the compiled database will allow the assessment of the existing predictive models for subduction-type events in terms of their applicability for the Central American region, which is essential for an adequate estimation of the hazard due to subduction earthquakes in this region.
