Although local and regional instrumental recordings of the devastating 26, January 2001, Bhuj earthquake are sparse, the distribution of macroseismic effects can provide important constraints on the mainshock ground motions. We compiled available news accounts describing damage and other effects and interpreted them to obtain modified Mercalli intensities (MMIs) at 200 locations throughout the ...

This paper investigates the collapse risk of seismically isolated buildings that are designed by procedures ASCE/SEI 7-16 standard for sites within 5 km active fault controls hazard. The study is based on six-story perimeter frame with special concentrically braced frames a location in California. seismic isolation systems considered this comprised either: (i) triple friction pendulum bearings ...

Seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. This devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.The base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...

and Applied Analysis 3 island of Taiwan. In this study, the chosen Kaohsiung Luchu science park is one of the major parks located in the southern part of Taiwan. This park has a total area of 571 hectares, which started construction in the year of 2001 and was completed in 2010. Various hightech industries, such as integrated circuits, precision machines, optoelectronic components, computer per...

The three principal New Madrid mainshocks of 1811–1812 were followed by extensive aftershock sequences that included numerous felt events. Although no instrumental data are available for either the mainshocks or the aftershocks, available historical accounts do provide information that can be used to estimate magnitudes and locations for the large events. In this article we investigate two of t...

considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

Abstract This paper describes a detailed numerical investigation into the inelastic displacement ratios of non-structural components mounted within multi-storey steel framed buildings and subjected to ground motions with forward-directivity features which are typical near-fault events. The study is carried out using multi-degree-of-freedom models 54 primary different structural characteristics....

In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. The considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...

Current studies lack probabilistic evaluations on the performance of fault-crossing bridges. This paper conducts seismic fragility analyses to evaluate cable-stayed bridges with effects fault ruptures. Synthetic across-fault ground motions are generated using existing simulation methods for low-frequency pulses and high-frequency residuals. Incremental dynamic analysis is utilized generate resp...
