The objectives of this test are to discuss what the structure seismic behaviors are under different lateral loading methods and to verify the school buildings retrofit methods. Four specimens were prepared to do following seismic tests: 1.Static Pushover Test, 2.Pseudo Dynamic Test, 3.Cyclic Loading Test, 4.Partition Walls Retrofitted by Composite Column Test, 5.Vertical Loading Redistribution Test, 6.Free Vibration, Force Vibration and Microtremor Measurement. The test results indicated that the ductility of school building under pseudo dynamic and cyclic lateral loading test was less than 50% of that under lateral pushover test and also the effect of partition walls retrofitted by composite column was verified. Besides, the dynamic amplifying coefficient of vertical loading redistribution was 2.69 when one column of structure was broken suddenly. Finally, we could obtain the natural frequencies of the buildings by these vibration tests. The measurement results indicated that the natural frequencies of the original structure was 2.71Hz and the retrofitted structure by composite column was 3.7Hz. All of the test results could be used to calibrate the seismic evaluation model. |
