Seismic performance of a bridge pier integrated by multiple steel pipes with directly-connected piles using soil-water coupled with three-dimensional elasto-plastic finite element analysis
A new type of bridge support using connected steel pipes was tested to see if it performs as well as traditional designs during earthquakes. Small-scale shaking tests showed that it works just as well or even better. However, since only one type of shaking was tested, we are now using computer simulations to see how it reacts to different kinds of earthquake motions. This will help us better understand how safe and reliable this new bridge design is for the future.
