Composite structure for bridges
Composite structure for bridges
(OP)
Steel-concrete (including lightweight concrete) composite structures are well known in building construction (static loading mostly). Could somebody share information/opinion of such structures subject to dynamic loading (bridges)?
May lightweight concrete be used as concrete component in composite structures for bridge spans?
Thanks.

RE: Composite structure for bridges
While I suspect there are many factors influencing this decision, what comes up most is durability and resilience in service life. Most DOTs prefer to design using something that will have a low maintenance cost rather than low initial costs.
However, when looking for ways to increase load capacity lightweight concrete is often used.
