STUDENT PILOT STATED THAT HE PERFORMED THE PREFLIGHT OF THE EXTERIOR AND INTERIOR USING THE POH CHECKLISTS BEFORE THE START OF THE ENGINE AND THAT THE PARKING BRAKE WAS SET. AFTER THE ENGINE WAS STARTED IT IMMEDIATELY WENT TO HIGH RPM AND BEGAN ROLLING FORWARD AND HARD LEFT, STRIKING THE STEEL BEAM OF THE OVERHANG PARKING STRUCTURE WITH THE LEFT WING. THE STUDENT PILOT STATED THAT THE BRAKES SEEMED INEFFECTIVE AS THE AIRCRAFT CONTINUED AROUND THE BEAM PIVOTING ON THE LEFT WING ALL THE WAS AROUND 3/4 OF A FULL TURN UNTIL THE AIRCRAFT STRUCK AND ROLLED OVER A CEMENT DIVIDER APPROXIMATELY 3 INCHES TALL, AT WHICH TIME THE AIRCRAFT ENGINE WAS STOPPED.
