The project entitled Global Ground Motion Prediction Equations is funded by the Global Earthquake Model (GEM) Foundation and has the objective of recommending a harmonized suite of ground motion prediction equations (GMPEs) that can be used at the global and regional scales for seismic hazard analysis and loss estimation studies. As part of this project, Task 1a experts were commissioned to mak...

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 ...

Urban planning rules and considering land use regarding faults can change the consequences of natural hazard such as earthquake. Vulnerability risk is increasing in Region 1 because of existence of the north fault, steep slopes and continuous construction of high-rise buildings. It is clear that Region 1’s Master Plan shouldn’t be prepared without considering natural hazard such as ...

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...

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...

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...
