Book excerpt: Lightweight concrete has been used frequently in the past for building structures, however, its limited use in bridges as well as questionable past earthquake performance have pointed towards the need to investigate the dynamic behavior. The research presented here represents the third phase of the lightweight concrete testing program at the University of California, San Diego, where the dynamic behavior of the material is considered. The results of the first two phases of testing indicated that lightweight concrete performs well with little decrease in shear and flexural strength under cyclic loading. The testing described here encompasses two test units subjected to earthquake time histories on the Shake Table. The objective of testing is to further verify the results of the first two phases of cyclic testing where shear and flexural response were considered, as well as to investigate the overall dynamic behavior. Results are presented in the form of a qualitative assessment of dynamic response as well as further verification of the recommendations presented during the first two stages of testing. Additionally, a steel jacket repair of the prestressed unit allowed investigation of the dynamic behavior of lightweight concrete after a damaging event and subsequent repair.
