“…The lumped mass, m, at the top of a multicolumn bent, at the height h from the ground level, was modelled in this simplified method. The stiffness of the bridge pier was expressed as k. The following steps were used for developing the analytical fragility curves [7,9], cf. Figure 1…”

“…The two distribution parameters, λ and ζ, are the mean and the standard deviation of ln X. See more detail about the functions in the research done by Karim and Yamazaki [9,22], Kibboua et al [7], and Kibboua [52]. They obtained the relation between the damage index DI created by Park and Ang [34] and a number of damage ranks, using the cumulative energy ductility, displacement, and ultimate ductility.…”

“…A comprehensive study, focusing on evaluation of seismic vulnerability of buildings, has been conducted in Algeria [4][5][6]. However, just a few studies have been carried out for bridges [2,7], although they constitute a key segment of transport infrastructure, highly important for daily life of residents and for economic development in general. Algeria has around 12000 bridges, out of which more than 90 % are ordinary bridges.…”

“…They constitute a useful tool for evaluating seismic vulnerability of structures. These curves can be developed either empirically, based on the damage reports from previous earthquakes [10,11], or analytically [7,[12][13][14][15][16]. Some researchers have developed these curves experimentally.…”

“…Karim and Yamazaki [9] used a simplified structural model to construct analytical fragility curves for bridge piers. In Algeria, Kibboua et al [7] developed analytical fragility curves for typical reinforced concrete bridge piers using a simplified approach. However, bridge components must absolutely be considered as a precondition for predicting real behaviour of such structures.…”

Using full bridge model to develop analytical fragility curves for typical concrete bridge piersThis study shows the effect of various numerical models on the development of analytical fragility curves for bridge piers. Two distinct models are compared: model with a single degree of freedom, and the proposed full bridge model. Bridge pier damage indexes are obtained by performing both dynamic and static nonlinear analyses (pushover and time history analysis), in order to develop fragility curves for this bridge pier. It was observed that capacity curves, ductility curves, and fragility curves, are sensitive to structural modelling.Primjena numeričkog modela cijelog mosta u analitičkom postupku izrade krivulja vjerojatnosti oštećenja U radu se analizira utjecaj različitih numeričkih modela mosta na definiranje krivulja vjerojatnosti oštećenja njihovih stupova analitičkim postupkom. Uspoređuju se dva različita modela, model s jednim stupnjem slobode te predloženi model cijelog mosta. Za potrebe određivanja krivulja vjerojatnosti oštećenja promatranog stupa, određeni su njegovi indeksi oštećenja pomoću dinamičke i statičke nelinearne analize (metoda postupnog guranja i time-history analiza). Utvrđeno je da način modeliranja utječe na krivulje nosivosti, duktilnosti i vjerojatnosti oštećenja. Ključne riječi: krivulje vjerojatnosti oštećenja, metoda postupnog guranja, seizmička oštetljivost, model stupa mosta Übersichtsarbeit Nadjib Hemaidi Zourgui, Abderrahmane Kibboua, Mohamed Taki Anwendung eines Vollbrückenmodells im analytischen Verfahren zur Erstellung der Wahrscheinlichkeitskurve der Beschädigungen In der Abhandlung wird der Einfluss verschiedener nummerischer Brückenmodelle auf die Festlegung der Wahrscheinlichkeitskurve der Beschädigungen ihrer Pfeiler durch ein analytisches Verfahren analysiert. Verglichen werden zwei unterschiedliche Modelle, das Modell mit einem Freiheitsgrad sowie das vorgeschlagene Vollbrückenmodell. Zum Zweck der Festlegung der Wahrscheinlichkeitskurve der Beschädigung des betrachteten Pfeilers wurde sein Beschädigungsindex mithilfe der dynamischen und statischen nicht linearen Analyse (Methode der inelastischen statischen Untersuchung und Time-history-Analyse) festgelegt. Festgestellt wurde, dass die Art der Modellierung die Tragfähigkeits-, Duktilitäts-und Wahrscheinlichkeitskurven der Beschädigung beeinflusst. Schlüsselwörter: Wahrscheinlichkeitskurve der Beschädigung, Methode der inelastischen statischen Untersuchung, seismische Beschädigbarkeit
