摘要
装配式混凝土结构由于质量可靠、生产效率高、抗震性能好,近年来在国内得到快速发展。框架柱作为框架结构的重要受力构件,预制柱之间的连接节点则更是其关键部位,节点连接的受力可靠性将决定整体结构的抗震能力,节点连接的构造合理性将影响施工效率与质量。结合近年来国内外装配式混凝土框架柱连接节点领域的发展概况,从试验研究与数值模拟两方面进行总结,并分析了仍然存在的问题及未来发展方向,为我国装配式混凝土框架结构的发展提供参考。
The prefabricated concrete structure developed rapidly in China in recent years due to its reliable quality,high production efficiency and good seismic performance. As the important force-bearing member of the frame structure,the frame column is the key part of the prefabricated column. The reliability of the joint connection will determine the seismic capacity of the whole structure. The structural rationality of the joint connection can affect the construction efficiency and quality. Combining with the development situation of fabricated concrete frame column connection joints at home and abroad in recent years, the experimental research and numerical simulation are summarized, and the existing problems and future development direction are analysed, which can provide a reference for the development of fabricated concrete frame structures in China.
