Seismic performance of hollow sectional columns with different portions of lap-spliced longitudinal bars

摘要

In the tests all columns failed in flexure showing displacement ductility over 6, which appeared to satisfy the ductility demand in moderate seismicity zones. It is desirable in establishing the performance-based design to provide various seismic details meeting the performance demand so that designers can choose a rational detail considering construction condition. This study has been served basic experimental data to meet that purpose.
