Accordingly, the study focused on considering all parameters affecting the choice of accelerogram pair for Tehran. For this purpose, a total of 1000 accelerogram pairs of the earthquakes that occurred in Iran during 1978–2010 were studied in terms of the parameters affecting the choice of appropriate accelerogram pair for Tehran, including distance to the epicenter, magnitude, frequency content, earthquake mechanism, soil properties, and configuration of ground layers. An important objective followed by preparing such a list was to appropriately match it to susceptibility and performance levels set in local design standards. For this purpose, seismic, statistical, and analytic studies were performed, finally ending up with a list of appropriate accelerogram pairs for time history analysis and design assessment in Tehran. In this research, to provide a proper understanding of the proposed list’s applied demands on the region’s structures, numerical and statistical studies and comparisons with the FEMA-P695 list have been done.</p>","PeriodicalId":50213,"journal":{"name":"Journal of Earthquake and Tsunami","volume":"242 2 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, ground motion models (GMM) for Arias Intensity and strong ground motion duration are developed based on recently compiled Chilean earthquakes records. The Chilean derived GMM are later compared with global and subduction models. For the duration case, two definitions are considered: significant duration and bracketed duration. Care is taken to consider newly define rupture areas for the major earthquake in the catalog, which allows to redefine the distances to be used in the analysis. The strong motion records are processed using robust techniques and standardized procedures. The model parameters are selected using a Bayesian updating method. This allows to estimate the parameters as well as their corresponding uncertainties recognizing the variability of the coefficients and of the selected model. The derived ground motion predictive model associated is validated through a residual analysis and probability distributions, obtained from the adjustment method. Additionally, for the bracketed duration analysis, a classification method based on Support Vector Machine (SVM) is used, with the aim to incorporate the records with duration of zero seconds. The comparison of the resultant model with the existing ones allows to confirm the differences that the tectonic Chilean environment produces, characterized mainly by a high relative convergence rate between plates and interplate thrust earthquakes with high magnitudes.","PeriodicalId":50213,"journal":{"name":"Journal of Earthquake and Tsunami","volume":"27 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89456858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of wave-flume tests were performed for [Formula: see text], with [Formula: see text] being the gap size and [Formula: see text] the pile diameter, to study the characteristics of the solitary-wave-induced local scour around a pile breakwater, including the scour-hole depth, scour-hole length, deposition sandbar height and the scoured volume. It was found that the jet flow through the gaps between piles caused the local scour around individual piles. A more or less two-dimensional deposition sandbar was found on the down-wave side of the pile breakwater in the later stage of the scour process. A new empirical equation was introduced to approximate the evolution of the depth of the scour hole induced by a series of solitary waves. The equation was verified by existing data reported in the literature for [Formula: see text] and the new data reported in this study. Effects of the distance between piles on the characteristics of the local scour were discussed by comparing the results for [Formula: see text] and 0.39. The comparison showed that the scour-hole depth and height of the sandbar for [Formula: see text] were all noticeably larger than the corresponding values for [Formula: see text].","PeriodicalId":50213,"journal":{"name":"Journal of Earthquake and Tsunami","volume":"106 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85260326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
