Construction Method and Mechanical Performance Analysis of a New Type of Truss Corbel Based on Topology Optimization
The rear-mounted corbel structure is widely used in the reinforcement and reconstruction of existing buildings.In order to obtain a more lightweight and efficient new corbel structure,this paper uses topology optimization technology to construct a truss-type corbel structure based on the existing"Π-shaped"steel corbel structure.The mechanical performance analysis of the corbel structure was carried out.First,a"Π-shaped"steel corbel model was established by Solidworks,and the model was topologically optimized by the simulation module.Then,based on the contour generated by the optimization,a herringbone support was set at the lower part,and Solidworks was used to draw again and optimize its size.Thus,a new truss corbel model is constructed.Finally,the finite element analysis of the newly constructed truss corbel structure is carried out,and the comparison with the"Π-shaped"steel corbel structure is discussed.The results show that the material consumption of the new truss corbel is only 57.3％of that of the"Π-shaped"steel corbel,and the torsion resistance is stronger and the stress distribution is more uniform.
