CCT Nodes Anchored by Headed Bars-Part 1: Behavior of Nodes
|
The anchorage behavior of headed reinforcement in compression-compression-tension (CCT) nodes was studied experimentally. Observations of cracking behavior and measurements of strains in ties and confining reinforcement, head slip, and node and strut capacities are reported. The behavior of unconfined nodes is compared with confined nodes. Insight into the stress state of the node is obtained through strain measurements along ties and along confining steel around the node. The strain data show node failure to be related primarily to anchorage of the tie bar. Additionally, the anchorage of ...
