About the research
The seismic performance of pier walls, hollow circular columns, and hollow rectangular columns confined with ties and cross-ties is crucial for the design of such systems. Large bridges with tall columns typically require hollow columns. There has been some limited testing of hollow columns, however, the analytical tools for design rely, to a great extent, on the models developed for solid columns. There is a need for improvement in the design and design analysis of hollow columns.
