摘要：

Diagonally reinforced coupling beams designed according to current codes are expected to endure significant inelastic deformations during earthquakes. However, it is very difficult to fabricate the coupling beams in a construction site due to the congestion of reinforcement and the complex arrangement of diagonal reinforcement. For resolving the problems, this study developed precast coupling beams with bundled diagonal reinforcement. To verify the effectiveness of the proposed design method, experimental tests were conducted on four 1/2-scale coupling beam specimens subjected to cyclic loading. The test results suggest that the precast coupling beams with bundled diagonal reinforcement exhibited good ductility and energy dissipation capacities similar to those having code-specified diagonal reinforcement.
