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-...

Nearly all residential houses were damaged due to 6.5 Mw earthquake in Pidie Jaya, 2016. The state of damage can be slight, moderate, and even extensive which lead the collapsing. confined masonry structure, commonly found Aceh, especially for housing construction, seemingly prone excitation. In this paper, analytical-based fragility curves are employed typical house structure. To account vario...

An experimental study was performed examining the effectiveness of a multi-compartment damper in attenuating response structures under random and earthquake excitations. The consisted four compartments unequal size; it mounted on small one-story steel structure. same number spherical particles were placed inside each compartment, resulting filling area ratios (the total squares around projected...

The nonlinearity of the soil may considerably affect response structures subjected to seismic events. This paper aims show under which circumstances geometry, soil, and earthquake-type; is important. A simple model based on a 1D shear column was developed calculate maximum strain (γ) in earthquake excitation. It found that γ function peak ground acceleration PGA horizontal displacement (∆). EC8...

Local fine-grained soils were usually used as backfill for geosynthetic-reinforced soil retaining walls (GSRWs). However, there are few studies on the seismic response in this case, especially under influence of rainfall. In study, three centrifuge shaking table tests performed at 30 gravities to investigate performance GSRWs subjected combined effect earthquakes and Two stages designed study. ...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

prediction using pure standards is expected to be biased whenever the slope of the calibration is affected by the presence of sample matrix. moreover, in the presence of unknown spectral interferents, first-order algorithms like partial least squares cannot be used. in this study, a method for determination of carvedilol (car) in tablet and urine samples is proposed by excitation-emission fluor...

In order to better research the role helicopter played in the earthquake rescue, a helicopter earthquake rescue mission modeling method based on multi-agent was proposed. The elements of the earthquake environment modeling were described. Typical helicopter rescue missions in earthquake relief were divided into three basic types, and the mission flow was carded. The division and function of age...

The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of ...
