Characteristics of ground motions close to the earthquake source can be considerably different from those of far-field motions which should be considered in design process of structures. The current study aimed to present new design response spectra for Iranian seismic design code taking into account the near-fault effects. For this purpose, a new attenuation relation based on the ground motion...

On Wednesday 6 April 1667, an earthquake occurred, and severely affected a large area of the eastern coast of the Adriatic Sea, also known as southern Dalmatia, in today Croatia, and part of Montenegro. This paper summarizes the seismological data existing today on this large earthquake, with special attention to how such data were gathered by means of investigating hitherto not considered hist...

Reinforced concrete (RC) structural walls are widely used in high-rise structures earthquake-prone areas. Damaged by the earthquakes past decades, these buildings need retrofitting order to increase resilience of with shear walls. This study aimed investigate RC wall using energy dissipation devices. To this end, a total four 15, 20, 25, and 30 stories equipped as their lateral load-resisting s...

S U M M A R Y We present hydrodynamic far-field simulations of the Aleutian tsunami of 1946 April 1, using both a dislocation source representing a slow earthquake and a dipolar one modelling a large landslide. The earthquake source is derived from the recent seismological study by López and Okal, while the landslide source was previously used to explain the exceptional run-up at Scotch Cap in ...

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...

A simple procedure to identify site frequencies using earthquake response records from roofs and basements of buildings is presented. For this purpose, data from five different buildings are analyzed using only spectral analyses techniques. Additional data such as free-field records in close proximity to the buildings and site characterization data are also used to estimate site frequencies and...

background: short golden time is important to save the injured in earthquake and to start search and rescue (sar) operation as soon as possible in affected regions. this study evaluated application of geographic information system (gis) for sar operation in rigan town, kerman province, which was hit by an earthquake of 6.3 richter scale on december 12, 2010 at 22:12. materials and methods: a gi...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...
