An Analysis Method on Post-earthquake Traversability of Road Network Considering Building Collapse

This study aims at quantifying the influence on the traversability of road network of road network caused by building collapse in earthquake. To this end, an analysis method on post-earthquake traversability of road network considering building collapse is proposed. First, the time-history analysis of seismic response based on the multi-degree of freedom (MDOF) model is performed for regional b...

Building Optical Constructions with Minimum Complexity

It is often claimed that future systems will necessarily be all-optical, because electronic devices are not fast enough to keep up with the increase in fiber capacity. However, two objections are commonly raised: first, optical systems need many basic optical components, which are typically very expensive; and second, optical systems need many switch reconfigurations, which are typically very s...

Controlled Building Collapse Analysis and Validation

Demolition of buildings at the end of their life cycle has become more and more important. These buildings are either no longer attractive in an architectural sense or did not reach sufficient standards. Especially industrial buildings which are no longer used because of technological or business reasons are often demolished by controlled explosives. To avoid damage of neighboring buildings or ...

Time parallel gravitational collapse simulation

This article demonstrates the applicability of the parallel-in-time method Parareal to the numerical solution of the Einstein gravity equations for the spherical collapse of a massless scalar field. To account for the shrinking of the spatial domain in time, a tailored load balancing scheme is proposed and compared to load balancing based on number of time steps alone. The performance of Parare...
