全预制装配式混凝土框架结构新型干式节点受力性能分析研究

Analysis and Research on Mechanical Behavior of New Type Dry Joint of Fully Prefabricated Concrete Frame Structure

在全预制装配式混凝土框架结构中,预制构件之间的连接会关系到整体结构的抗震性能和结构抗倒塌能力,连接节点对结构性能起到决定性的作用。在对提出的新型干式连接节点(柱-柱和梁-柱方钢管法兰盘连接)的受力性能、传力构造特点等进行研究分析的基础上,通过理论分析推导出新型干式节点的承压、受弯、受剪等承载力计算公式,以期得到新型全预制装配式框架新型干式连接节点的设计建议。

In prefabricated concrete frame structures, the connection between prefabricated components will affect the seismic performance and collapse resistance of the whole structure,the connection joint plays a decisive role in the structural performance. In this paper, based on the research and analysis of the new type of dry joint(column-column and beam-column square steel tube flange connection) of the mechanical performance and t force structure, Through theoretical analysis, the calculation formulas of bearing capacity are derived under pressure, bending and shearing, In order to get some suggestions for the new dry-type joints in the full prefabricated concrete frame structure.
