In order to improve the accuracy of risk analysis, authors propose a seismic fragility analysis method using two ground motion intensity measures; peak ground acceleratio [...]

We propose the probabilistic seismic hazard map for the study of earthquake risk of spatially-spreaded facilities. This is introduced as the conditional seismic hazard ma [...]

In the traditional mix proportion of anti-washout underwater concrete, the unit content of water and cement were much larger than that of normal concrete. The authors stu [...]
