Distributed, high-performance earthquake deformation analysis and modelling facilitated by Discovery Net
نویسندگان
چکیده
A Discovery Net project that has been investigating the relationship between macro and micro-scale earthquake deformational processes has successfully developed and tested a geoinformatics infrastructure for linking computationally intensive earthquake monitoring and modelling. Measurement of lateral coseismic deformation is carried out with imageodesy algorithms running on servers at the London eScience Centre. The resultant deformation field is used to initialise geo-mechanical simulations of the earthquake deformation running on supercomputers based at the University of Oklahoma. The paper describes detail of this project, initial results of testing the workflow, and follow-on research and development.

Prediction of Permanent Earthquake-Induced Deformation in Earth Dams and Embankments Using Artificial Neural Networks
This research intends to develop a method based on the Artificial Neural Network (ANN) to predict permanent earthquake-induced deformation of the earth dams and embankments. For this purpose, data sets of observations from 152 published case histories on the performance of the earth dams and embankments, during the past earthquakes, was used. In order to predict earthquake-induced deformation o...
متن کاملNumerical Modelling of Timber Braced Frame Masonry Structures (Dhajji Dewari)
This paper presents numerical modeling technique for Dhajji-Dewari structures (timber-braced rubble stone masonry), and its application for the evaluation of in-plane force-deformation capacity of Dhajji wall panels of different configuration of bracings. Dhajji structures are mainly composed of vertical and horizontal timber posts and braced using diagonal bracings and horizontal studs. Wall o...
متن کاملModelling Role-Playing Games Using PEPA Nets
We present a performance modelling case study of a distributed multi-player game expressed in the PEPA nets modelling language. The case study provides a modern complex distributed application programming problem which has many inherent communication and synchronisation complexities which are subtle to model accurately. We put forward the position that a high-level performance modelling languag...
متن کاملDeformation Performance of the Karkheh Earth Dam with Mixed and Pure Clay Coreunder Seismic Excitations
The number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. Nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. In the past, earth dams usually designed with pure clay core, but in recent decades t...
متن کاملEstimating the inter-story drift in high rise buildings with the flexural and shear cantilever beam and mode-acceleration method
In this study, the seismic inter-story drift of structures is estimated by a combination of mode-acceleration equations with the modelling of high-rise buildings with flexural and shear cantilever beams. In the equation presented for calculating the inter-story drift, having less knowledge of the building is adequate and this issue is of significance in estimating the nonstructural component fo...
