| We made an experiment to research the dynamic behavior of reinforced concrete（RC）bridge piers．In the experiment，a pier model-mounted carriage was made to collide against a concrete wall with a buffer to exert an impact load on the base．A weight was used as a dead．load．The response acceleration of the weight was measured to experimentally examine the dynamic behavior of RC bridge piers，including their damage．[*]As a result，the following poinsts were clarified．（1）This experimental method is relatively useful in understanding the dynamic behavior of reinforced concrete bridge piers．（2）The transmission mechanism from input acceleration to response acceleration was obtained．（3）Once a plastic hinge hax been formed at one point，the damege at that point alone is severe |
