We obtained the rupture process and slip distribution of 2022 Mw6.6 Menyuan earthquake by jointly inverting accelerogram data InSAR measurements. The near-field measurements provide good constraints on shallow distributions (<6 km). enable us to better resolve deeper coseismic (>6 combination two types provided improved constrains earthquake. results from joint inversion reveal a 26-km-lo...

Seismic investigation revealed that a fault fracture zone is one of the most vulnerable areas mountain tunnels in earthquakes. For tunnel crossing secondary fault, may be permanently dislocated by causative faults during earthquakes, making subject to combined action seismic motion and dislocation, which makes response more complicated. In order investigate fault-crossing this case explore suit...

The purpose of this study is to develop a new system for measuring leg motions using a portable three-dimensional accelerometer. The measuring system is composed of acceleration sensors (Micro Stone, MA3-10Ac), a data logger, a data reader, and a personal computer. The personal computer draws a graph of the acceleration of movements (i.e., accelerogram) from the output signals of the accelerati...

The present project aims to present an alternative method for the determination of the inelastic displacements using pushover analysis and directly generated inelastic spectra. The determination of the target displacement is similar to Fajfar`s N2 method, employed in Eurocode 8. Unlike the EC8, where empirical formulas are used for describing the inelastic seismic demand, the proposed method us...

Ground cylindrical steel fluid storage tanks are widely used in different industries. Regarding the significance of these structures, it is important to establish their proper performance in earthquakes by evaluating their seismic performance. The present study examines the seismic behavior of an unanchored fluid storage system via ABAQUS after validation using an experimental model. Next, the ...

through the last three decades different seismological and engineering approaches for the generation of artificial earthquakes have been proposed. selection of an appropriate method for the generation of applicable artificial earthquake accelerograms (aeas) has been a challenging subject in the time history analysis of the structures in the case of the absence of sufficient recorded accelerogra...

In this paper, we consider the numerical justification of possibility to construct a low-cement content concrete gravity dam as an alternative traditional solution with rockfill in Pskem HPP canyon on river Uzbekistan Republic. The calculation studies were performed using finite element method (FEM), considering non-linear (elastoplastic) behavior and foundation rock ANSYS software package. Sei...

The on-site earthquake early warning system is under development for the area near the earthquake epicenter to provide information such as earthquake magnitude, the arrival time and the intensity of the strong shaking for free field as well as the structural response, etc. The real-time strong motion signals recorded from Taiwan Strong Motion Instrumentation Program (TSMIP) were used to train n...
