Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...

A hierarchical family of Damage Probability Matrices (DPM) has been derived in this paper from the ones implicitly contained in the EMS-98 Macroseismic Scale for 6 vulnerability classes. To this aim the linguistic definitions provided by the scale, and the associated fuzzy sub-sets of the percentage of buildings, have been completed according to reliable hypotheses. A parametric representation ...

In order to understand the seismic performance and mechanism of bottom frame seismic wall masonry structure (BFSWMS) and its vulnerability in empirical seismic damage, based on the statistical and numerical analysis of the field seismic damage observation data of 2178 Dujiangyan structures in the Wenchuan great earthquake urban of China on May 12, 2008, a non-linear function model between the s...

Applying renormalization group theory to evaluate the safety of overall structure, local damage probability must be obtained at first. According to the results of unit detection test and numerical simulation, the methods how to determine local damage probability was presented in the paper. For small unit, meaning the unit size is far less than the maximum primitive cell or the structure size, i...

We consider the problem of accurately recovering a matrix B of size M ×M , which represents a probability distribution over M2 outcomes, given access to an observed matrix of “counts” generated by taking independent samples from the distribution B. How can structural properties of the underlying matrix B be leveraged to yield computationally efficient and information theoretically optimal recon...
