Abstract The joint probability distribution of different intensity measures at sites in one earthquake is needed to define the stochastic process regulating exceedance (in time) ensemble sites, which turn a funding element so‐called multi‐site probabilistic seismic hazard analysis (MSPSHA). simplest model for event requires mean vector and covariance matrix all conditional magnitude location ea...

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 design of critical facilities needs a targeted computation the expected ground motion levels. Trans Adriatic Pipeline (TAP) is pipeline that transports natural gas from Greek-Turkish border, through Greece and Albania, to Italy. We present here probabilistic seismic hazard analysis (PSHA) we performed for this facility, deaggregation results, aiming identify dominant sources select...

Recent experimental research has shown that ordinary unbounded steel reinforced elastomeric bearings (SREBs) can be considered as an attractive cost-effective option for the seismic isolation of highway bridges. To further investigate its benefits, the current study is focused on the seismic risk assessment of an optimally designed highway bridge isolated by SREB system. A typical three-span hi...

Abstract Ground motion scenarios exists for most of the seismically active areas around globe. They essentially correspond to shaking level maps at given earthquake return times which are used as reference likely under threat from future ground displacements. Being landslides in actively regions closely controlled by motion, one would expect that landslide susceptibility should change patterns ...

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...

This paper summarizes the results of a comprehensive study carried out to assess the seismic response of a 59-span bridge, considering Soil-Structure Interaction (SSI). The bridge was built in the early seventies at a distance of about 5 km from a major fault. The methodology adopted to idealize the bridge and its foundation system for elastic and inelastic analysis is briefly described. The SS...

Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...
