| 摘 要： | 为考虑扁梁柱节点内、外核心区的相互作用,对扁梁柱节点的内、外核心区进行了重新划分,认为内、外核心区有一个重叠的区域,给出了地震作用在扁梁柱节点内外核心区的分配方法,采用压杆模型和软化桁架模型,提出扁梁柱节点的设计方法。该方法可以考虑节点核心区钢纤维和扁梁中无粘结预应力对扁梁柱节点抗剪极限承载力的作用。该设计方法的可靠性得到四个钢筋混凝土扁梁柱节点试验数据的验证。

| Abstract: | In order to consider the mutual effect of the interior and exterior core of flat beam-column joints,the author deems that there is an overlapped region between interior core and exterior core.Seismic actions transmitted to the interior and exterior cores are determined according to the principle proposed by the author.Using a compression strut model and a softened truss model,this paper provides a design method of reinforced concrete flat beam-column connections.The effects of steel fibers mixed in joint cores and unbonded prestessed tendons in flat beams on the ultimate shear resistant capacity of reinforced concrete flat beam-column connections are included in the proposed method.The reliability of the proposed design method is verified by the test data of four reinforced concrete flat beam-column connections. |
