6.3: The RLC Circuit
As in the case of forced oscillations of a spring-mass system with damping, we call (Q_p) the steady state charge on the capacitor of the (RLC) circuit. Since (I=Q''=Q_c''+Q_p'') and (Q_c'') also tends to zero exponentially as (ttoinfty), we say that (I_c=Q''_c) is the transient current and (I_p=Q_p'') is the steady state current. In ...

Why is a capacitor considered a short circuit at start up?
The voltage across a capacitor can not change instantaneously so the initial voltage across the capacitor is 0. The capacitor then charges to the value of the input voltage and current stops flowing. Under this steady state condition its impedance seems to be infinite.

It kind of depends on what you mean by a DC circuit. If it involves e.g. a DC voltage source that is instantaneously connected to an LC combination of an inductor and a capacitor with zero-resistance wires, then no, a steady DC state is never reached -- but presumably that''s not what you meant.
