“…The post-seismic investigation of constructions in Algiers was carried out in the case of the 2003 event but not in the case of 1980. The percentages in terms of the level of damage reported in relation to all the constructions are shown in Figure (13). This shows that the ratio of constructions classi ed "red" according to the EMS98 scale is respectively 1.3%; 0.1% and 2.4% for the three districts considered by this study.…”

During earthquakes affecting urban areas, we often deplore damages to buildings. The pattern of these damages depends on the characteristics of the event, the site response, and the vulnerability of exposed structures. The old urban center of Algiers is a densely populated district. Preserving human lives is therefore of primary importance. Soil-structure interaction is an important factor in site-wide risk assessment. When the ground and supported buildings have similar frequencies, this interaction induces a phenomenon called resonance. In this study, the Standard Penetration Test (SPT) and the Horizontal-to-Vertical Spectral Ratio (HVSR) of microtremors techniques were applied in order to evaluate the fundamental frequencies of the ground; as well as the fundamental, longitudinal, and transverse frequencies of each selected building. This investigation aimed to detect the existence of the resonance phenomenon. If we assume that the sample of buildings tested is representative of the urban district of the area studied, we can conclude that buildings in the old center of Algiers, are not exposed to a resonance phenomenon. The same conclusion was observed from the analysis of the results of the post-seismic investigations obtained from two major past earthquakes, El Asnam on 10/10/1980 and Boumerdes on 21/05/2003. The first one is considered as a distant event from Algiers, while the second one is at a nearby location.

During earthquakes affecting urban areas, we often deplore damages to buildings. The pattern of these damages depends on the characteristics of the event, the site response, and the vulnerability of exposed structures. Algeria is among the countries having the highest seismic hazard in the Mediterranean basin. The old urban center of Algiers the capital of Algeria, is a densely populated district. Preserving human lives is therefore of primary importance. Soil-structure interaction is an important factor in site-wide risk assessment. When the ground and supported buildings have similar frequencies, this interaction induces a phenomenon called resonance. In this study, the Standard Penetration Test (SPT) and the Horizontal-to-Vertical Spectral Ratio (HVSR) of microtremors techniques were applied in order to evaluate the fundamental frequencies of the ground; as well as the fundamental, longitudinal, and transverse frequencies of each selected building. This investigation aimed to detect the existence of the resonance phenomenon. If we assume that the sample of buildings tested is representative of the urban district of the area studied, we can conclude that buildings in the old center of Algiers, are not exposed to a resonance phenomenon. The same conclusion was observed from the analysis of the results of the post-seismic investigations obtained from two major past earthquakes, El Asnamon 10/10/1980 and Boumerdeson 21/05/2003. The first one is considered as a distant event from Algiers, while the second one is at a nearby location.

“…Soil-structure interaction has been given great attention by researchers and scientists. Considerable research was carried out on structure resting on shallow foundations (Parmelee 1967;Kausel and Roësset 1974;Bielak 1975;Aviles and Perez-Rocha 1998;Mylonakis and Gazetas 2000;Tabatabaiefar and Massumi 2010;Fnais et al 2015;Ozcelik and Sarp 2017). The case of deep foundations like piles and micropiles has also attracted a great attention (Shahrour et al 2001;Shahrour 2004, 2006;Medina et al 2013;Maravas et al 2014).…”

Influence of soil–structure interaction on the fundamental frequency of shear wall structures

et al. 2020

View full text Add to dashboard Cite

Numerous studies indicate that soil-structure interaction has a great influence on the dynamic characteristic of buildings. This study presents an analysis of the effect of soil-structure interaction (SSI) on the natural frequency of shear wall building structures. The system is modeled by a 3D finite element model and using elastic discrete springs to represent the soilstructure interaction. A parametric study for different soil profiles is performed on one-storey building followed by a generalization on multi-storey buildings. Analysis of the results leads to the definition of the relative soil-structure parameter K ss for this type of structures. A multi-regression analysis allows to set up a dimensionless chart for the assessment of the fundamental frequency of shear wall building structures.
