Expansion joints in short span structures

The objective of this exercise could be redefined as the "elimination/reduction in the number of expansion joints in a short span structure". The report discusses how this can be achieved both in terms of new structures and also how the same theory can then be applied in existing structures to reduce the number of expansion joints. The report also discusses how this principle could be extended in using reinforced concrete driven piles as they are proven to be most economical in bridge design and construction in short span structures. Section 4 of this report discusses how the principles developed for the design of new bridges without expansion joints can be adopted to existing structures. This discussion is provided by using examples of typical short span bridges that can be found in Victoria. It considers how these existing structures can be modified to reduce the number of expansion joints in the structure. Due to the variability of existing structures it is recommended that these be only used as a guide and every bridge be analysed to assess the possible modifications that could be implemented to reduce/eliminate the number of expansion joints in that structure.
