Abstract:
This paper describes research related to the use of lightweight concrete for bridge column construction in seismic regions. Of interest is the behavior of columns dominated by shear as well as those dominated by flexure. A series of large-scale experimental tests was performed to assess the response of reinforced lightweight concrete columns in the inelastic range. Results indicate that a reduction in shear and flexural strength is appropriate for lightweight concrete, while displacement capacity and energy dissipation are not affected in a significant manner.
