Abstract

A method of modifying strain characteristics of a bridge construction having a support structure for a deck plate. The method includes actively evacuating air from within the internal cavity to create a negative pressure differential in the internal cavity relative to its environment. Also described is a bridge construction with one or more pumps to provide a negative pressure differential within support structures for a deck plate of the bridge construction.
