The main components which affect the earthquake damage grades classification of multistory masonry buildings and the damage characters are summarized and analyzed through the statistics and analysis of a large number of previous earthquake damage data. According to the standard of earthquake damage grades classification, the damage numbers of each component of multistory masonry buildings under...

In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

This paper introduces the damage statistics of reinforced concrete buildings after the 1985 Mexico Earthquake, the 1990 Ruzon (Philippines) Earthquake, the 1992 Erzincan (Turkey) Earthquake, and the 1995 Hyogo-ken Nanbu (Kobe) Earthquake. These data were obtained in severely damaged areas in each earthquake through the inventory damage investigation of the Architectural Institute of Japan teams...

damage to essential facilities (e.g. lifelines and industrial facilities) due to extreme loads may cause remarkable indirect impact as well as direct physical loss. hence understanding seismic performance of essential facilities is very important in high seismic risk regions. on october 23, 2011 an earthquake of magnitude mw7.2 occurred in van province in eastern turkey. several damages occurre...

The 2015 Gorkha Nepal earthquake caused tremendous damage and loss. To gain valuable lessons from this tragic event, an earthquake damage investigation team was dispatched to Nepal from 1 May 2015 to 7 May 2015. A unique aspect of the earthquake damage investigation is that first-hand earthquake damage data were obtained 6–11 days after the mainshock. To gain deeper understanding of the observe...

Most of the existing seismic design codes are based on the empirical knowledge accumulated through systematic earthquake damage data collection and their analysis. Required levels of protection and seismic design forces gradually are increased after each series of catastrophic earthquakes particularly in developed countries. Many efforts have been made through experimental and analytical studie...

According to the features and demands of earthquake rescue on-site, automatic modelling and scene generation methods based on fundamental geographic data were investigated, and an earthquake scene model was proposed considering both effect of local site conditions on ground motion and vulnerability of different buildings. Based on ArcGIS Engine, the system in which the scene of pre-earthquake a...

This paper is a progress report of a MCEER research project on the development of multihazard protection technologies for critical facilities. One important component is to consider earthquake and earthquake induced hazards (e.g. fire, haz-mat leakage, power outrage, etc). This paper is concerned with earthquake and subsequent fire hazards. Records from historical earthquakes show that sometime...
