钢管混凝土板柱节点弯矩分析

Analysis on the Bending Moment of Steel Pipe Column-Slab Connection

利用有限元分析软件对钢管混凝土板柱铰接节点的应变、内力及变形进行了分析,结果表明:发生侧移时该节点附加弯矩很小,可认为此节点为铰接点,在对节点进行抗冲切设计时可不考虑节点附加弯矩的影响,只需进行重力荷载作用下的冲切设计。

The strain, inner force and deformation of the joint in slab-column connection was studied with the help of ANINA. The result showed that the additional bending moment was low and could be regarded as a hinge. When designing the punching resistance, we could only conduct the design under the gravity load regardless of the additional bending moment of the connection
