Empirical Seismic Vulnerability and Damage of Bottom Frame Seismic Wall Masonry Structure: A Case Study in Dujiangyan (China) Region
In order to understand the seismic performance and mechanism of bottom frame seismic wall masonry structure (BFSWMS) and its vulnerability in empirical seismic damage, based on the statistical and numerical analysis of the field seismic damage observation data of 2178 Dujiangyan structures in the Wenchuan great earthquake urban of China on May 12, 2008, a non-linear function model between the s...
متن کاملAssessment of active tectonic with Using geomorphic indicators and GIS in Maragheh region basins (East Azerbaijan, Northwest Iran)
Introduction Paleoclimatics studies can respond the many uncertainties about past climate change; an issue that is being studied seriously in the world but less attention has been paid in Iran. The Late Quaternary can be considered as Holocene. Holocene, which spans over 11,000 years ago; In general, it is considered as a period with relatively warm and stable climatic conditions. However, rec...
متن کاملQuantitative evaluation of neo-tectonic and morpho-tectonic activities at the north and northwest of Damghan (Eastern Alborz)
1- Introduction: Geomorphic investigation is a powerful tool for studies of active tectonics in active regions. Active faults and folds commonly have topography that can assist in identifying different geomorphic or structural segments along a structure, and estimating the potentially most active segments. In tectonically active regions, drainage networks and topographic features can be used as...
متن کاملFuzzy Control of Seismic Structure with an Active Mass Damper
Fuzzy theory is highly promising for active structural control. The advantage of fuzzy controllers over classical controllers is the limited number of measured structural responses used to implement the control rules and its intrinsic robustness. In this paper, Fuzzy rules were generated firstly by learning from sample data obtained from the performance of the system under optimal control algor...
متن کاملRepeating seismic events in China.
About 10% of seismic events in and near China from 1985 to 2000 were repeating events not more than about 1 kilometer from each other. We cross-correlated seismograms from approximately 14,000 earthquakes and explosions and measured relative arrival times to approximately 0.01 second, enabling lateral location precision of about 100 to 300 meters. Such precision is important for seismic hazard ...
