摘要

本文对钢筋混凝土梁柱节点在地震作用下的性能改进提出了建议。目的是评估低强度混凝土在接缝中使用无箍筋的素筋。另一个目的是研究上述条件下循环荷载作用下节点的行为。在试验过程中，制作了5个不同配筋配置的试件并进行了试验。基于研究结果，得出结论:节点中箍筋的布置以及梁纵向钢筋中至少90度吊钩的使用是现有结构性能的关键参数。

Seismic load tests on exterior beam-column connections of existing RC structures

Recommendations for enhancement of performance of RC beam-column joints under seismic effects are presented in this study. The aim is to evaluate the use of lowstrength concrete with plain bars without stirrups in the joints. An additional aim is to study behaviour of joints in the aforementioned conditions under cyclic loading. Five specimens with various reinforcement configurations were produced and tested in the experimental process. Based on results obtained in the study, it is concluded that the stirrup arrangement in the joints, and the use of at least 90-degree hooks in longitudinal reinforcement of beams, are critical parameters for the performance of existing structures.
