Abstract:
This paper discusses four aspects related to the seismic behavior of structures composed of lightweight concrete. Following a brief discussion of the merits of lightweight concrete, the past seismic performance of the material is discussed. The second portion of the paper discusses research that has been conducted on the seismic behavior of lightweight concrete structures and research on parameters that influence the seismic behavior of lightweight concrete. This is followed by a discussion of various existing code-based provisions that have an effect on the seismic design of lightweight concrete structures. Lastly, the paper concludes with a discussion of future research needs.
