Mechanical behavior of buildings subjected to impulsive motionsBulletin of Earthquake Engineering - Tập 14 - Trang 849-862 - 2015
Mariella Diaferio, Dora Foti
This article analyses the response of steel-moment resisting frames subjected to near-field ground motions. In near-field areas high damage and a relevant number of collapsed steel buildings arose even when both design and detailing had been performed in perfect accordance with the code provisions. These circumstances are related to the characteristics of the motion that in such areas shows large-...... hiện toàn bộ
Correlations between Vs and SPT-N by different borehole measurement methods: effect on seismic site classificationBulletin of Earthquake Engineering - Tập 18 - Trang 1139-1159 - 2019
Chih-Chieh Lu, Jin-Hung Hwang
The average shear wave velocity of the top 30 m of the subsurface profile (Vs30) is a critical parameter to characterize the seismic site class. Since Vs30 is a quantitative index and measurable by geophysical techniques, the use of Vs30 becomes popular and is widely used in practice. However, the Vs30 of a site may vary due to the different Vs measurement methods used. This could result in a diff...... hiện toàn bộ
Damage assessment of modern masonry buildings after the L’Aquila earthquakeBulletin of Earthquake Engineering - Tập 18 - Trang 2275-2301 - 2020
Bruno Calderoni, Emilia Angela Cordasco, Marta Del Zoppo, Andrea Prota
This paper deals with the structural behaviour and the damage assessment of Italian “modern” masonry buildings during seismic events. “Modern” masonry buildings are characterized by a box-like structural behaviour, due to the presence of effective connections between horizontal floors and vertical load-bearing walls, which prevents local mechanisms such as the overturning of external façades durin...... hiện toàn bộ
Seismic behaviour of high-rise frame-core tube structures considering dynamic soil–structure interactionBulletin of Earthquake Engineering - Tập 20 - Trang 5073-5105 - 2022
Xiaofeng Zhang, Harry Far
As the population grows and land prices rise, high-rise buildings are becoming more and more common and popular in urban cities. The traditional high-rise building design method generally assumes the structure is fixed at the base because the influence of soil–structure interaction is considered to be beneficial to the response of structures under the earthquake excitation. However, recent earthqu...... hiện toàn bộ
Operational earthquake loss forecasting: a retrospective analysis of some recent Italian seismic sequencesBulletin of Earthquake Engineering - Tập 14 - Trang 2607-2626 - 2015
Eugenio Chioccarelli, Iunio Iervolino
Operational earthquake forecasting (OEF) relies on real-time monitoring of seismic activity in an area of interest to provide constant (e.g., daily) updates of the expected number of events exceeding a certain magnitude threshold in a given time window (e.g., 1 week). It has been demonstrated that the rates from OEF can be used to estimate expected values of the seismic losses in the same time int...... hiện toàn bộ
