Bridges

Structural analysis has progressed a long way from hand calculations and the use of distribution factors. From the first computer methods, grid and grillage analysis techniques evolved, leading through progressive enhancements to the advanced 3D graphical and analytical tools that we see and use today. Now, finite element (FE) analysis is being used more and more for bridge engineering because of the more economical and accurate assessments and designs its use can produce. This paper illustrates the role that it can play in just some areas of bridge analysis, assessment and design with reference to a number of projects in the UK, US and Australia.
