Earthquake resistant bridges columns

The video discusses the destructive impact of earthquakes on bridges and introduces a research initiative led by Texas A&M University and the University of Colorado Boulder, funded by the NSF. The research explores alternative bridge structures, specifically Hybrid Sliding Rocking (HSR) columns, which are designed to withstand seismic activity without sustaining damage. These columns consist of concrete segments held by steel cables, allowing them to shift and rock. The adoption of HSR columns could prevent bridge damage, maintain access to affected areas, save lives, and speed up community recovery post-earthquake.

Describe the construction method of the hybrid sliding rocking (HSR) columns.

What benefits do HSR columns provide in the event of an earthquake?
