Abstract


Since the 20th century, The rapid development of Steel, Machinery manufacturing, railway, port and construction greatly promote the application of Steel structures. Then the construction machinery and tall buildings need a higher security. For many case, the performances of steel structures derictly affect the security of machinery and buildings. So the main Object is still about performances of steel structures, and the performances of steel structures is made of stability, Strength, stiffness and fatigue. The stability of steel structures is the main Subject of this paper.The reseach of theory about stability of steel structures has already become perfect. And in the Practical engineering, designers offen design by code for steel structures though Manually calculating,and the efficiency of this method is very low.so how to improve its efficiency and keep the Accuracy is an unsolve subject.This paper take the several simple steel structures as the research objects.Using the finite element analysis software ANSYS to simulate the structures for analyzing the stability of steel structures. And the Technology pathway is:Firstly, design it by code for steel structures though Manually calculating; secondly, using the software ANSYS to simulate the structures for analyzing the stability of steel structures, then compare the results of them.In the end, take the Summary of the way to slove the subject of stability of steel structures by Numerical Analysis method.This paper is doing the work as the Following Steps:1) Take the Beam, Column, Panel as the research objects,get the Critical load from Manually calculating with the code for steel structures.2) Using the software ANSYS to simulate the structures for analyzing the stability of steel structures by Eigenvalue buckling analysis.3) Using the software ANSYS to simulate the structures for analyzing the stability of steel structures by Nonlinear buckling analysis.4) Compare the result of the all above, take the Summary of the way to slove the subject of stability of steel structures by Numerical Analysis method.
