有关半刚性节点的研究始自上个世纪初,但在研究初期,并未引起学者们足够的重视。梁与柱的连接是高层钢结构节点设计中的关键,半刚性连接的节点引起结构的内力重分布,且具有较强的耗能能力。国内外学者在节点以及框架两方面做了许多工作,从上个世纪60年代至今,国内外有关半刚性节点弯矩-转角关系的研究资料非常多,并取得了丰硕的研究成果,仅数学模型就有十余种。
Research on semi-rigid nodes started in the early part of the last century, but in the early stage of the study, scholars did not pay enough attention. The connection between the beam and the column is the key point in the design of high-rise steel structure nodes. The semi-rigidly connected nodes cause the redistribution of the internal forces of the structure and have a strong energy dissipation capability. Domestic and foreign scholars have done a lot of work in both nodes and frameworks. From the 1960s to the present, research data on the relationship between moments and angles of semi-rigid joints at home and abroad have been very numerous, and fruitful research results have been obtained. Only mathematical models have been obtained. There are more than ten species.
