Comparison on Mechanics Performance of Concrete Column Frame Structure with Prefabricated Cage System

摘要

According to the requirements of the project in this paper, the frame structure with reinforced concrete columns and prefabricated cage system concrete columns are designed. Then the Pushover finite element simulation analysis is carried out under the action of one-way increasing load. After that, the axial force, the bending moment, the displacement and the inter-story drift of RC columns and prefabricated cage system concrete columns are analyzed and compared. Research shows that: under the condition of the same material and the same strength, the mechanics performance of the prefabricated cage system is better than that of the traditional reinforced concrete column. The deformation capacity of the prefabricated cage system concrete columns is slightly higher than that one. Therefore, the mechanics performance of prefabricated cage system is better, and the ductility requirements are fulfilled.
