What is the purpose of columns in piers?

The purpose of columns in piers is to provide vertical support. In the design of structures such as bridges, piers serve as critical components that transfer the load from the bridge deck down to the foundation. These columns are designed to withstand forces exerted by the load on the deck as well as environmental factors like wind and seismic activity.

By distributing the vertical load effectively, columns ensure the structural integrity of the pier and the overall stability of the bridge. They are usually designed to bear significant weight and are often reinforced to handle the stresses they encounter. The focus on vertical support underlines the importance of maintaining alignment and balance in the structure, which is essential for its functionality and safety.
