Dysfunctions and failures of buried pipe networks, like sewer are studied in this paper from the point view structural reliability heterogeneity geotechnical conditions longitudinal direction. Combined soil spatial variability Peak Ground Acceleration (PGA) induce stresses displacements. A model has been developed within frame geostatistics a mechanical description soil–structure interaction se...

Background: Earthquake-prone regions from the stable continental regions (like Peninsular India) warrant total seismic hazard estimation from possible sources — reservoir induced or tectonic. The Koyna region falls in the so-called stable continental region, though previously considered as aseismic because of its location in the Peninsular India, which was argued to be the continental Shield re...

Many researches have been currently conducted on the effects of fault distance on structures revealing that their seismic response can differ according to their distance from the fault. Suspension bridges due to their long period and high flexibility can be more sensitive to this phenomenon, especially in vertical vibration. Since the engineers tend to use longer spans, the length factor should...

At 3:08 on 6 September 2018 (UTC +9), massive landslides were triggered by an earthquake of Mw 6.6 that occurred in Hokkaido, Japan. In this paper, a coseismic landslide inventory covers 388 km2 the earthquake-impacted area and includes 5828 with total 23.66 was compiled using visual interpretations various high-resolution satellite images. To analyze spatial distribution characteristics landsl...

Although convolutional neural networks (CNN) have been applied successfully to many fields, the onsite earthquake early warning by CNN remains unexplored. This study aims predict peak ground acceleration (PGA) of incoming seismic waves using CNN, which is achieved analyzing first 3 s P-wave data collected from a single site. Because amplitude large and small earthquakes can differ, multi-scale ...

Earthquake research has not yielded promising results because earthquakes have uncertain data parameters, and one of the methods to overcome problem parameters is nonparametric method, namely Multivariate Adaptive Regression Splines (MARS). Sumbawa Island part territory Indonesia in position three active earth plates, so prone earthquake hazards. Therefore, this important do. This study aimed a...

The study on seismic vulnerability of thermal power plants is great significance for damage prevention the electrical system and risk analysis economic loss. This paper presented a method obtaining matrix curve based beta function. Firstly, according to results in American ATC-25 report, expected values indexes under different intensities were calculated. It was assumed that substation plant sa...

The paper describes an integrated approach to seismic hazard assessment, which was applied for the Taiwan region. First, the theoretical seismic catalogue (2001-2050) for the Taiwan region had been calculated using the 4D-model (location, depth, time) for dynamic deformation of the Earth’ crust and 5D-model (location, depth, time, magnitude) for seismic process. The models were developed on the...

This paper presents uniform risk spectra for zero stiffness bilinear elastic (ZSBE) systems. The ZSBE oscillator is a system with post-“yield” that satisfactorily predicts the response of different systems negative lateral (e.g., free-standing or restrained rocking blocks). It can be described by single parameter; thus, it simpler to produce its spectrum. Using proxy, this provides sites in six...
