Abstract |
This study focuses on the seismic performance of high-rise apartment building structures composed of dry-jointed precast (PC) moment-resisting frames. The objective is to ensure that a dry-jointed PC frame meets the performance level of a PC intermediate-moment frame. To this end, a steel bracket-type connection device was developed to connect the bottom rebars of the PC beam to the column, and both experimental and analytical studies were conducted to evaluate its performance. The experimental study was conducted in two stages. In the first stage, the performance of the connecting device was evaluated according to the KS D 0249 standards for mechanical joints of reinforcing bars. In the second stage, three full-scale test specimens of the PC structure were manufactured and tested to determine whether they met the performance conditions outlined in the draft KDS earthquake-resistant design code. In parallel, nonlinear analysis and performance evaluation using ASCE/SEI-41 were conducted to further assess the experimental results. The results demonstrated that the beam-column dry joint of the PC apartment building frame, which is the subject of this study, can achieve earthquake-resistant performance equivalent to that of a PC intermediate moment frame
