Abstract
An elastic-plastic dynamic analysis method based on the beam elements is developed in
order to investigate the dynamic behavior of PC beams under impact loading. First, the
limit dropping height in the impact test is predicted by the high speed loading analysis.
Second, the impact test is performed in order to confirm the failure behavior of the
bonded and unbonded PC beams by using the newly built weight dropping machine.
Finally, the impact failure analysis is developed in order to simulate the results obtained
by the impact test.
1 Introduction
Generally, it is said that a prestressed concrete (PC) structure has both advantages of
short construction period and high strength of a PC member. However, it has become
required to improve the deformability as well as the high strength of a
