Connector Moment and Forces at Hinge

[ruzfactor]

Hello all,
I am having some issues with the moment and forces at hinge connector. I am running a dynamic implicit analysis, and extracting time history output of CTF and CTM. CTM along axial direction is zero which makes sense. But I am trying to understand how abaqus calculates the moment in hinge connectors. Is this based on global coordinate or local nodal coordinate?

I have used two wire elements to create a hinge connection.

Node-1--------Node-2--------Node-3

Element-1: Node 1 & 2
Element-2: Node 2 & 3

I assume the moments (along other two directions )in the two elements should be similar. But I am getting significant differences. That's why if anyone could suggest how CTM and CTFs are calculated for the two elements connected to create a hinge, would be helpful to understand. Thanks in advance.

Node order (which node is defined as the first one) matters for the interpretation of connector outputs, including moments.

Nodes are defined in ascending order
I.e. 1,2,3
El1: 1,2
EL2: 2,3

CT outputs are requested for El1 and El2. As I mentioned, the moments and forces are significantly different for two elements. Makes me wonder how the CT outputs are calculated for the elements.
