Abstract

A new structure named reinforced concrete grid moment-resisting frame (RC-GMRF) have been adopted in high-rise buildings in China. However, complex construction due to numerous beam-column joints restricts the application of this structure. A novel precast reinforced concrete GMRF (PC-GMRF) is proposed in this paper to solve this problem. Three specimens, including one traditional reinforced concrete moment-resisting frame (RC-MRF) as reference, were tested under reverse cyclic loading to evaluate the seismic performance. All three specimens were designed using the same amount of construction material. The experimental results showed that PC-GMRF exhibited comparable seismic performance with that of RC-GMRF. The load-carrying capacity, initial stiffness and energy dissipation capacity were improved by an average of 43%, 29%, and 21%, respectively, compared with those of RC-MRF. This study indicated that the performance of PC-GMRF was acceptable and could be used in the moment-resisting frame as a novel structure.
