It is important for us to knowhow to prevent us from being hurt in earthquake . The most effective way is to depend on ourselves. We can get everything ready before it happens . We must keep enough food and drinking water with us . When it happens keep calm and dont run about .follo...
"When a bridge fails or collapses, it kind of immediately disrupts the transportation network around it," Alexander said. "It can disrupt daily commutes. It can disrupt freight movements and therefore business supply chains and even emergency responses." One way around this is diversifying modes ...
However, the packing fraction collapses data only at high porosity and becomes increasingly insufficient in dense textures, where the disorder becomes a controlling factor, see Supplementary Fig. S8a. To account for the disorder effects at low porosity, we assume \({C}_{D}^{{\prime} }={f}...

Scientists are working on tiny sensors to place in cement and other materials so the physical condition of the infrastructure itself can be detected before structural issues lead to disasters such as bridge collapses. Cars are getting smarter, too. GPS in cars has been a thing for years, and ...

8 of the Most Devastating Bridge Collapses The disasters had a wide range of causes, from marching soldiers to a crowd gathered to witness baptisms. Read more How ‘Dune’ Imagined Climate Disaster—and Inspired Environmental Activism Frank Herbert’s 1965 science fiction novel, ‘Dune,’ tackled...
Ship collisions and their impact on bridges are a similar area of evolving understanding and improved design codes. There have been over 35 major bridge collapses globally that were caused byship collisions from 1960 to 2015. Engineers evaluate the failures, and they update the engineering codes so...
