The frame given in the figure below has three degrees of freedom in C (1,2,3) and three degrees of freedom in B (4,5,6) . In Figure 1: Open the vertical deformation at node C and apply force F and close the other degrees of freedom. Now , If we separate the CD column and the BC beam According to the stiffness method What is the status of the forces and moment on the CD in C? In other words, what is the ratio of forces R1 F R3 R4 R5 R6 Apply to CD column in C? And what is the position of the forces and anchors on BC in B and C? In other words, what is the ratio of forces R1 F R3 R4 R5 R6 Applied to BC beams in C and B?
The frame given in the figure below has three degrees of freedom in C (1,2,3) and three degrees of freedom in B (4,5,6) .
In Figure 1:
Open the vertical deformation at node C and apply force F and close the other degrees of freedom.
Now , If we separate the CD column and the BC beam
According to the stiffness method
What is the status of the forces and moment on the CD in C? In other words, what is the ratio of forces R1 F R3 R4 R5 R6 Apply to CD column in C?
And what is the position of the forces and anchors on BC in B and C? In other words, what is the ratio of forces R1 F R3 R4 R5 R6 Applied to BC beams in C and B?
In Figure 2:
Open the rotation at node C and insert the momentM and close the other degrees of freedom.
Now , If we separate the CD column and the BC beam
According to the stiffness method
What is the status of the forces and moment on the CD in C? In other words, what is the ratio of forces R1 R2 M R4 R5 R6 Apply to CD column in C?
And what is the position of the forces and anchors on BC in B and C? In other words, what is the ratio of forces R1 R2 M R4 R5 R6 Applied to BC beams in C and B?
