Analysis of the Principle, Applications and Improvements of Foldable Structure for Bridge Design

As a matter of fact, the foldable structures have been widely adopted in these years. With this in mind, collapsible structures in Bridges are mainly studied and investigated in this research. The development history of foldable structure is discussed. And how folding structures have been gradually used in construction projects such as the famous London Bridge throughout history. Several common foldable structures and their principles include their advantages and disadvantages and the difficulty of implementation. It is also briefly stated in the article. The foldable structure of several representative bridge projects from 2022 to 2024 has also been demonstrated. The paper then describes the development direction of foldable structure in the future, the defects of foldable structure and the possible impact of environmental protection on the material selection of foldable structure. The purpose of this paper is to summarize the existing collapsible structures of Bridges with famous engineering projects in the past four years as examples. Combined with the social background, the future development direction of the structure is analyzed and predicted.
