影响现浇框架节点设计的因素分析

依据国内外大量的钢筋混凝土现浇框架结构节点试验结果和震害分析,简要介绍了钢筋混凝土现浇框架结构节点受力特点、破坏机理、和设计准则等,阐述影响现浇框架节点抗剪承载力的主要因素。最后从保证框架整体结构的安全可靠、经济合理和便于施工等方面提出几点建议,作为节点区设计、施工的参考。

Analysis of Influence Factor to Joint Design of Cast-in-site Frame Work

According to the large quantity of the experimental results and the analysis of seismic hazards of the joint of cast-in-site frame structure at home and abroad,this paper simply introduces the feature of force,the mecha- nism of fracture and the design criterion of the nodal regions of cast-in-site framework,and analyzes the major factors which affect the shear force resistance of the joint of cast-in-site framework.At last,this paper presents some sugges- tions that guarantee the whole structure of fiamework safe and reliable,economical and rational,and facilitate to con- struct,and are used as reference in design and construction of the nodal regions.
