Table 1

Research content and conclusion.

1	By using the finite element analysis software ABAQUS, the finite element model of reinforced concrete shaped column is established based on the test data in the relevant literature, and the accuracy of the model establishment is analyzed by verifying the load-displacement curve and ultimate bearing capacity obtained after the test
2	On the basis of verifying the correctness of the analytical finite element model, the cross-sectional form of reinforced concrete shaped column is designed, the relevant specimen parameters are set, and the specimen parameters required to be studied under each working condition are determined, and then, the finite element models are established separately to obtain the concrete stress cloud, reinforcement stress cloud, and load-displacement curve under the structural form of eccentricity, loading angle, concrete, strength and reinforcement ratio
3	Compare and analyze the changes of concrete stress cloud, steel stress cloud, and load-deflection curve of the shaped column under different working conditions and the damage pattern of the specimen, respectively, and determine the influence law of the mechanical properties of the shaped column under the above four working conditions and one-way bias pressure
