摘要
通过分析各几何参数对地震作用下KK型节点计算结果的影响,获得了节点动力特性随其几何参数的变化规律,找出了有利于节点抗震设防的各种因素,即增大支、主管的外径比β和支管同主管厚度之比τ,减小主管径厚比γ、支管同主管轴线间夹角θ以及空间管节点支管轴线间横向夹角。
By analyzing the geometric parameters of the earthquake under the impact of nade-KK on the results,access to the node with the dynamic properties of their geometric parameters of the changes found in favor of earthquake-proof node of a variety of factors,the increased support,in charge than the outside diameter of β and the branch in charge of the same thickness ratio τ,in charge of reducing the diameter than the thick γ,with branches in charge of inter-axis angle θ,as well as space control node branch angle between the horizontal axis between .
