Vpp for American split-phase 110V AC
Place a high resistance (perhaps 1M ohm) from your + to - output. Now there is a closed circuit which includes 2 diodes and a resistor. Where is the source in that loop ? (You didn't say you wanted voltage to GND)  

Then you edited in a capacitor, which is ok.  

LT Spice simulator might or might not be trusted.  

Along with seeing no source in your loop,  LT Spice agrees that voltage is zero.  

The voltage at the cathode of D1 (my circuit), with respect to ground is 340 volts peak to peak.  (  I used 120 VRMS  ).  

The OP did state to use 110 VRMS. The voltage at the cathode of D1 (my circuit), with respect to ground is then 310 volts peak to peak.
