Re: Mainshock-aftershock sequences
sendSelf and recvSelf are not implemented correctly for the elements and materials you are using.
Which elements and materials are in your model?

Re: 3DRCframe-Vertical frequency/period/eigenvalue
There is no difference between "horizontal" and "vertical" periods. Periods are periods.
Define mass and stiffness in the vertical direction and you will get an eigenvalue that corresponds to vibration in the vertical direction.

Re: BoucWen Material Yield Point
I don't know all the details, but check Table 5.1 and Figure 5.5 of the Haukaas and ADK PEER report shown on the wiki page.

Re: pushover analysis
You are using truss elements with 3 DOF/node in a 2D model, so the rotational stiffnesses are all zero.

Re: Chord rotation recorder
The chordRotation recorder gives the basic deformations of the element - axial deformation plus nodal rotations relative to the element chord.
