Abstract
This paper analyzes the influence of different floor parameters on the seismic performance of RC frame core tube structure by finite element method. The results show that within a certain range, with the increase of plate thickness and reinforcement ratio, the ultimate load and ultimate displacement of the structure increase; the influence of plate thickness, bottom reinforcement ratio, and roof reinforcement ratio on the seismic performance of the structure is: the reinforcement ratio of the top of the board > the reinforcement ratio of the bottom of the board > the thickness of the plate; the stress of the main beam near the core tube is the highest, the stress of the side beam is second, the stress of the core tube is between the two, and the stress of the floor reinforcement is generally lower than the main beam.
