This paper discusses the critical role of transportation systems in disaster recovery and the development of any long-term economic effects from earthquakes, based on insights from the Kobe earthquake and other disasters. The occurrence of long-term effects on regional economies has been controversial in the disaster literature and are for the most part ignored in earthquake loss estimation mod...

Most instruments used in seismological practice to record ground motion are pendulum seismographs, velocigraphs, or accelerographs. In most cases it is assumed that seismic instruments are only sensitive to the translational motion of the instrument’s base. In this study the full equation of pendulum motion, including the inputs of rotations and tilts, is considered. It is shown that tilting th...

We used continuous recordings in Sichuan, China to track the temporal change in elastic properties of the medium, namely the seismic speed, at a regional scale in a 2 year period which includes the great Wenchuan Mw 7.9 earthquake. The data are recorded by a temporary network of 156 broad-band seismographs, in a 200km × 200km region that covers the southern 2/3 of the fault system activated dur...

When transitioning local laboratory practices into distributed environments, the interdependent relationship between experimental procedure and the technologies used to execute experiments becomes highly visible and a focal point for system requirements. We present an analysis of ways in which this reciprocal relationship is reconfiguring laboratory practices in earthquake engineering as a new ...

An analysis method called macro-micro analysis method has been proposed to compute strong ground motion distribution with highest spatial and temporal resolution, which is based on multi-scale analysis. Strong ground motion (SGM) simulator with high-resolution is developed using this analysis method. Basic validity is verified by comparison with measured data. Prototype of Integrated Earthquake...

It was presented in the previous joint panel in 2011 that we have made a proposal on method for evaluating the long-period earthquake motion time history with periods from 0.1 to 10 second using designated earthquake magnitude, shortest distance to the source area and location of hypocenter in view of establishing the generation scheme for design long-period motions for super high-rise building...

The earthquake is usually a big disaster that causes several death and mortalities. Post earthquake crisis is an important situation for management. The recent 2015 Nepal earthquake is one of the most destructive earthquakes in history. In post earthquake crisis, lack of facilities, destroyed of infrastructures and limitation of transportation can be expected. This can superimpose the situation...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...
