State: California Abstract:
The purpose of this study was to develop precast column details that are able to dissipate energy under seismic loads. Several innovative precast concrete columns were designed then studied experimentally on a shake table and analyzed. Two types of precast bridge columns were studied, including segmental columns and monolithic columns. Compared to standard precast concrete segmental columns (those with no monolithic connection between the base segment and the footing), all specimens showed superior performance with minimal residual displacement and larger energy dissipation. Testing and analysis of a 0.3-scale two-column bent incorporating two precast columns, precast footing, and a precast cap beam found that the seismic performance of both columns was satisfactory and that the pipe-pin connections performed well.
