This paper studied the regional seismic tectonic characteristics, activity near-field earthquake characteristics about site of Seismic Microzonation in Shangluo City, belts and potential source zone were divided, calculating risk analysis bedrock site, surveying engineering geological conditions carrying out response zoning ground motion parameters site. The above results provide a basis for fo...

The recent Mw 9.0 off the Pacific coast of Tohoku earthquake is the largest recorded earthquake in Japan’s history. The Tohoku main shock and its aftershocks generated widespread strong shakings as large as ∼3000 Gal along the east coast of Japan. Wu and Peng (2011) found clear drop of resonant frequency of up to 70% during the Tohoku main shock at 6 sites and correlation of resonance (peak) fr...

This paper presents site-specific probabilistic seismic hazard analysis (PSHA) results at 24 locations throughout New Zealand (NZ). Specifically, peak ground acceleration (PGA) curves for two generic soft soil conditions are considered. For specific return periods of interest, disaggregation is used to obtain the percentage contributions various sources hazard, including metrics such as mean ea...

In site-specific site-response assessments, observation-based approaches requiring a target–reference recording pair or regional network cannot be implemented at many sites of interest. Thus, various estimation techniques have to used. How effective are these in predicting site responses (average over earthquakes)? To address this question, we conduct systematic comparison using large data set ...

failure of the quay walls due to earthquakes results in severe economic loss. because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. this study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

Abstract To ensure environmental and public safety, critical facilities require rigorous seismic hazard analysis to define input for their design. We consider the case of Trans Adriatic Pipeline (TAP), which is a pipeline that transports natural gas from Caspian Sea southern Italy, crossing active faults areas characterized by high seismicity levels. For this pipeline, we develop Probabilistic ...

The New Madrid seismic zone is the most important regional seismic hazard in middle America, having produced several very large earthquakes in historic and geologic time. In this study we simulate time histories in Memphis, Tennessee, and St. Louis, Missouri, for M 7.5 and M 8.0 earthquakes along two faults in the New Madrid seismic zone. Simulations are based on a well-established and calibrat...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

This paper investigates the integrated riser/vessel system which is subjected to random waves. Riser pipelines are the main components of the oil and gas offshore platforms. Whereas Iran country has been located on the fringes of Caspian Sea deep water, therefore study and research in this area is increasingly essential. The fluctuation of floating production causes the severe response and grea...
