Numerical Simulation Analysis of Damage Evolution Process of Steel Structure Beam Column Reinforced Joint Frame
To explore the effects of different factors on the damage evolution process of steel structure beam column reinforced joint frames.Four steel structure beam column strengthened joint frame specimens were selected as experimental objects.On the basis of Ceteris paribus,the axial compression ratio of the specimens,the thickness of the steel cover plate and the strength of the concrete were changed.ABAQUS software was used to simulate the steel structure beam column strengthened joint frame,observe the stress nephogram of the damage evolution process,and make statistics on the yield displacement and peak displacement.Conclusion:During the damage process of the steel structure beam column reinforced joint frame,the axial compression ratio and the thickness of the steel cover plate have little effect on the mechanical performance.The concrete strength has a significant impact on the mechanical performance.Moreover,as the concrete strength increases,the bearing capacity of the steel structure beam column reinforced joint frame also increases.In the design of the joint frame,the concrete strength should be appropriately increased to improve the bearing capacity of the joint frame.
