Background: The seismic retrofitting of frame structures using hysteretic dampers is a very effective strategy to mitigate earthquake-induced risks. However, its application in current practice rather limited since simple and efficient design methods are still lacking, the more accurate time-history analysis time-consuming computationally demanding. Aims: This paper develops applies retrofit me...

Abstract This paper intends to provide quantitative seismic response characteristics of steel moment resisting frames (MRFs) with inelastic beam‐to‐column panel zone joints. Two modeling approaches are proposed for this purpose along a methodology consider the fracture potential at bottom beam flange in MRFs due kinking. Both approaches, which validated available experiments, preserve behaviora...

This paper proposes a macro-model for simulating the hysteretic behavior of composite-steel beams as part fully restrained beam-to-column connections in moment-resisting frames (MRFs). Comparisons with experimental data suggest that proposed model captures asymmetric response including cyclic deterioration strength and stiffness. Moreover, primary slab-column force transfer mechanisms predicts ...

In this article we develop a model for the commodity price dynamics under the risk-neutral measure where the spot price switches between two distinct stochastic processes depending on whether or not inventory is being held. Specifically, whenever the drift of the spot price exceeds the cost of carrying inventory (interest rate plus storage costs) the inventory is being held. Conversely, wheneve...

Multi-hazard risk assessment may provide comprehensive analysis of the impact multiple hazards but still needs to resolve major challenges in three aspects: (1) proper consideration hazard inter-dependency, (2) physically based modelling interactions, and (3) fully quantitative show probability loss. Compound flooding is a typical multi-hazard problem that involves concurrence drivers, e.g. hea...

In this paper, we give a ‘direct’ construction of the endomorphism ring of supersingular elliptic curves over a prime field Fp from ‘ideal classes’ of Q( √−p). We use the result to prove that the result of Kaneko on ‘minimal’ CM liftings of such supersingular elliptic curves is a best possible result. We also prove that the result of Elkies on ‘minimal’ CM liftings of all supersingular elliptic...

background: in northeastern iran there is an area of high incidence of esophageal cancer which is populated by residents of turkmen ancestry. several environmental risk factors for esophageal cancer have been proposed, but the roles of familial and genetic factors have not been studied extensively in the turkmen population. materials and methods: we evaluated the importance of familial risk fac...

The derivation of probabilities of high wind speeds and the establishment of risk curves for storm damage is of prime importance in natural hazard risk analysis. Risk curves allow the assessment of damage being exceeded at a given level of probability. In this paper, a method for the assessment of winter storm damage risk is described in detail and applied to the German state of Baden-Württembe...

In probabilistic seismic hazard analysis, one wants to calculate the probability of exceedance of a certain shaking level at a particular site. This requires a good understanding of the parameters that can influence seismic ground-motions. Bayesian networks are used to investigate the probabilistic dependencies between several parameters of the groundmotion domain. Problems specific to the doma...
