Application of the Endurance Time Method in the Seismic Assessment of Moment-Resisting Reinforced Concrete Frames with Setbacks [PDF]
مدلسازی پیشرفته در مهندسی عمرانNowadays, many buildings around the world exhibit height irregularities. Given that higher vibration modes can significantly influence the responses of irregular frames, it is essential to investigate the seismic behavior of these structures.

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

SEISMIC BEHAVIOR OF A ROCK TUNNEL
Doboku Gakkai Ronbunshu, 1986 In order to investigate seismic behavior of a rock tunnel, earthquake observations have been carried out in the Shin Usami Tunnel of JNR's Line, located in Ito City of Shizuoka prefecture. From an analysis of earthquake records observed from July 1983 to June 1985, the following results were obtained.(1) The direction of the predominant motion of an ...

Is It Possible to Predict Strong Earthquakes?
, 2014 The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent ...

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Cyclic test and parametric analysis of steel shear wall made of two inclined slotted infill plates
Nuclear Engineering and TechnologyThis study investigates the seismic performance of a steel shear wall (SSW) made of two inclined slotted infill plates. Despite widespread use of SSWs, conventional steel shear walls (C-SSWs) face challenges such as limited energy dissipation and ...

Seismic Behavior of Masonry Cloister Vaults
Academia XXII, 2018 This paper presents the results of an investigation into earthquake resistance and the behavior of historical masonry cloister vaults. In a previous paper,1 the authors presented a simpli ed structural analysis approach, called the “strip method of analysis,” to assess the lateral load behavior of a relatively shallow cloister vault. In this paper, two

Textile mills in Friuli (XIX-XX century). Building technique analysis and seismic refurbishment [PDF]
, 2018 The conservation of industrial architectures and the refurbishment project, must take into account the growing attention to the seismic risk of the built heritage, which the recent events of central Italy have made dramatically current.
