Narrative: During cruise flight; we had several electrical malfunctions. Some we could correct and some we couldn't. Lost #1 Approach Path; #1 Flight Director; #1 pressure regulator; #1 pitch trim; landing gear system 1; First Officer (FO) alpha probe heat. We complied with ECAM's and QRH. Stabilized the situation and continued on to destination. Number 1 AP came back so I took the aircraft back. In the pattern; we got an ECAM #2 FO pitot heat fault. Complied with ECAM and turned off. When we extended the gear; the FO noticed that we had no antiskid release bars. Cycled brake antiskid switch with no help. No QRH help for this. Elected to land with antiskid off and manual brakes. Runway length was not an issue and was dry. After touchdown; I went into full reverse thrust until 80 knots without any problems. When I transferred to the tiller for steering; it was jammed. I had to use differential braking to keep aircraft on the runway. I had no way to steer off the runway. Came to a stop and advised the tower and had safety equipment called out. Did not declare an emergency. Crash crew evaluated the aircraft and said they saw no hydraulic leaks or broken parts around nose wheel. Maintenance towed us off the runway to our gate.


Second narrative: While enroute aircraft encountered spurious failure of the #1 Flight Director;#1 Autopilot; #1 Pitch Damper; FO's pitot heat; #1 Cabin Pressure controller; ECAM directed selection of #2 Landing Gear indicating system. Crew followed ECAM and QRH procedures recovering lost systems or selecting secondary systems except FO's Pitot Heat and #1 Pitch Damper. After recovery of #1 Autopilot Captain resumed role of pilot flying. As a precaution crew decided to descend from FL350 to FL310 and slow to Mach .77 allowing a larger flight envelope margin in the event of a secondary failure of the Pitch system. Upon reaching the terminal area during approach check the ECAM directed the FO pitot heat be placed in the off position and crew complied. After gear was selected down to land ECAM had no Brake Release indicators on the display. Switch position was verified; crew opted to land with the Brake/Anti-Skid switch in the ALT/OFF position. Touchdown and roll out were normal until approx 50 kts when the pilot flying announced; 'No nose wheel steering.' He brought the aircraft to a stop while pilot monitoring informed the tower of the inability to clear the runway. As a precaution crew had the fire department look over the aircraft and follow us to our ramp while maintenance towed the aircraft to the gate. No emergency was declared. Maintenance found a failed Proximity Box and detector; replaced the component; ran checks and returned the aircraft to service. Components fail.


Synopsis: A300 flight crew reported multiple electrical failures in cruise. Crew followed QRH procedures recovering lost systems and upon landing; it was discovered that nose wheel steering was inoperative.
