ABSTRACT

In order to study the seismic performance of prefabricated concrete pier with slot connection, based on the Rongwu new line highway bridge project, this paper uses finite element analysis software ABAQUS to carry out the numerical simulation analysis of three kinds of fully prefabricated concrete pier with slot connection under different axial compression ratio, focusing on their bearing capacity, hysteretic characteristics, skeleton curve and ductility. Also, fully prefabricated slotted pier specimens were designed and manufactured to carry out the quasi-static test. The results show that with the increase of axial compression ratio, the bearing capacity of slotted pier increases gradually, while the failure rate of bearing capacity grows faster, and the ductility coefficient also decreases. When the axial compression ratio is about 0.2, fully prefabricated slotted pier has better seismic performance.
