The Research on Seismic Response of Prestressed Concrete Flat Beam in Pseudo-dynamic Test

摘要

By carrying out pseudo-dynamic test on an unbonded and a bonded prestressed concrete flat beam separately, their dynamic properties and seismic responses can be learned; also seismic resistance can be compared. The test results show that framework with prestressed concrete flat beam has certain energy-absorbing capacity, and no matter bonded form or not it makes little influence on overall seismic performance and failure form. In addition, the beam-column strength ratio should be increased properly in design.
