Analysis of the seismic risk to a structure requires assessment of both the rate of occurrence of future earthquake ground motions hazard and the effect of these ground motions on the structure response . These two pieces are often linked using an intensity measure such as spectral acceleration. However, earth scientists typically use the geometric mean of the spectral accelerations of the two ...

Seismic hazard analyses, either in a deterministic (DSHA) or probabilistic (PSHA) framework, are both commonly adopted for evaluating earthquake risk. Although different in methodology, both approaches involving tedious calculation are certainly a computer-aided analysis. For Taiwan, a few PSHA studies have been conducted, but not a single comprehensive DSHA study is yet available for this regi...

This paper conducts a detailed review of the seismic hazard, inventory, bridge vulnerability, and bridge retrofit practices in the Central and Southeastern United States CSUS . Based on the analysis of the bridge inventory in the CSUS, it was found that over 12,927 bridges 12.6% are exposed to 7% probability of exceedance PE in 75-year peak ground acceleration PGA of greater than 0.20 g, and ne...

Abstract The seismic performance and safety of major European industrial facilities have a global interest for the whole Europe its citizens. However, design these is based on national, sometimes outdated hazard analyses. results commonly developed, fully harmonized newly released Seismic Hazard Model ESHM20 provide pertinent reference at scale been officially adopted as an “acceptable represen...

This paper presents a study to statistically characterize the joint earthquake-snow hazard and subsequently develop maximum inter-story drift fragility curves for a series of archetype woodframe structures. Of particular focus are structures built in heavy-snow regions where seismic design may govern (and hence the roof snow load contributes additional seismic mass). While load standards such a...

Seismic hazard assessment in several sites worldwide depends on two or more seismic sources. Many countries affected by subduction zones have strong motions earthquakes originated at least important In Mexico, interplate (subduction process) epicenters located the Pacific coast with hypocenter depths less than 45 km and intraplate (intermediate-depth earthquakes) normally inside continent depth...

INTRODUCTION Hypotension causes diffuse liver injury accompanied by increased local production of interleukin-6 (IL-6) in swine models of uncontrolled hemorrhagic shock (HS). IL-6 is transcriptionally up-regulated by nuclear factor (NF)-kappaB and results in activation of signal transducer and activator of transcription-3 (Stat3) in a murine model of controlled HS. Our objectives were: 1). to d...

Uncombable hair syndrome (UHS) is a rare disorder of shaft morphology. UHS presents in early childhood with blonde, dry and frizzy scalp hair. The rate growth may be normal or slow. characterized by triangular shape longitudinal grooves along the axis. At writing, no curative treatment available for UHS. However, research suggests that oral biotin supplementation results clinical improvement te...

This study develops a novel simulation-based procedure for the estimation of the likelihood that seismic intensity (in terms of spectral acceleration) and tsunami inundation (in terms of wave height), at a particular location, will exceed given hazard levels. The procedure accounts for a common physical rupture process for shaking and tsunami. Numerous realizations of stochastic slip distributi...
