Shake Table Tests of Segmental Bridge Column with Match-Cast Dry Joints

Abstract eng:
In the paper, the seismic performance of segmental bridge column with match-cast dry joints was investigated through a series of earthquake simulator tests. The research objectives were to investigate the effect of cast-in-placement construction method to pre-cast segmental construction, to compare the damaging effects of existing of energy-dissipating device, and to assess the different dynamic response with the same skeleton curve between cast-in-placement specimen and pre-cast segmental specimen. Then performance of each column was examined using some measures. Comparing the response of each specimen to the same runs, the relative displacement demand of the pre-cast segmental bridge column with samller enengy-dissipation capacity is large than that of a conventional cast-in-place reinforced concrete bridge column.
