【 摘 要 】

Suggestions for improving seismic performance of beam-column connections of the existing RC structures are presented in this paper. The use of low-strength concrete with plain bars without stirrups in joints is analysed, and behaviour of joints in the aforementioned conditions under cyclic load is investigated. Five specimens with different reinforcement configurations were produced and tested in the experimental process. Based on results, it was concluded that critical parameters for the performance of existing structures are: stirrup arrangement in joints, and the use of at least 90-degree hooks in longitudinal reinforcement of beams.
