Abstract
NO METHODS EXIST WORLDWIDE TO TEST MAJOR BUILDINGS, IN-PLACEAND AS CONSTRUCTED, TO EARTHQUAKE MOTION-TIME HISTORIES UP TO AND INCLUDING DAMAGE AND COLLAPSE LEVELS. TESTING COMPLETE CIVIL STRUCTURES AT SIGNIFICANT EARTHQUAKE LEVELS CAN PROVIDE MUCH NEEDED INFORMATION FOR PROTECTION AGAINST BUILDING FAILURES, AND IN TURN TO IMPROVE HUMAN SECURITY ANDSAFETY. PHASE I RESEARCH IS TO FIND THE FEASIBILITY AND VALIDITY OF SIMULATING MOTIONS ON A SIZABLE STRUCTURE BY USING COLD GAS PULSE GENERATORS THAT DUPLICATE STRONG MOTIONEARTHQUAKES. PHASE II WILL BE DEVOTED TO EXPERIMENTS AND RESEARCH ON HIGH PRESSURE STEAM PULSE GENERATORS FOR REPETITIVE PULSES WITH THRUSTS FROM 50,000 TO 75,000 LBF. OPERATIONAL FEATURES OF PORTABILITY AND EASE OF SET-UP AND OPERATION REMAIN AS REQUIREMENTS IN SPITE OF THE HIGH PRESSURES, HIGH TEMPERATURE, AND SURGE SUPPRESSION, AND THESE MUST BE ACCOMMODATED. TWO UNITS WILL BE BUILT, AND RESEARCH AND EXPERIMENTS ON THESE UNITS WILL BE MADE IN ORDER TO GENERATE THE REQUIRED OPERATING CHARACTERISTICS. PHASE II WILL CONTINUE DEVELOPING THE COLD GAS APPARATUS (RATED AT 10,000 LBF.) FOR OPERATIONAL USE. STUDIES WILL BEMADE FOR APPLICATION TO SMALL BUILDINGS, LARGE EQUIPMENTS, PIPING SYSTEMS, OPEN-FRAME STRUCTURES, AND POWER DISTRIBUTION CENTERS.
