However, the<br>connections may diminish the increase in the utilization due to their complication in the installation work and<br>seismic design consideration. This paper presents an easy-to-install steel box for column base connection<br>designed based on the standard capacity design criteria. Experimental investigations on the precast concrete<br>columns using the steel box connection at the column base under cyclic loading were also made. The test<br>results show the satisfactory seismic performance of the precast specimens both in seismic shear capacity,<br>ductility and energy dissipation compared with the identical cast-in-place specimen. The failure of the precast<br>columns, with proper details, was in the flexural ductile mode. The shear capacity was respectively 1.16-1.24<br>times higher than the averaged capacity of the cast-in-place column. The damping ratio was about 18-25<br>percent in the inelastic range, after the drift ratio of 3.0%. Finally, the seismic performance of the designed<br>precast concrete column using the steel box connection based on the capacity design criteria is guaranteed<br>without early brittle failures.</p> ER -
