摘要

Hollow-core concrete columns have been used for very tall bridge columns in seismic areas including New Zealand, Japan and Italy. Hollow-core cross-sections reduce the mass of the column, which reduces the bridge self-weight contributing to the inertial forces during earthquakes. Hollow-core columns also reduce the required foundation dimensions, thereby substantially reducing construction costs. These advantages have increased the use of hollow-core columns instead of similar solid members. In addition, the hollow-core columns are more sustainable than the solid cross-section columns, as they use less concrete.
