By using finite element software ABAQUS, the nonlinear finite element analysis of earthquake resistance behavior of T-shaped concrete-filled rectangular composite steel tubular columns is carried out, furthermore, the analysis results and the corresponding experiment results are compared. The results indicate that the calculated value of ultimate bearing capacity is less than the experimental value, and the results of FEM analysis can match the experiment results better, and thus, it can better reflect the earthquake resistance behaviors of the specimens.

The determining of m value in “m” method has great significance to force analysis of pile foundation buried segments. In this paper, a finite element software is used for the nonlinear finite element analysis of elastic long pile under the horizontal force action, and combined with the related provisions and formulas for “m” method given in 《Code for Pile Foundation of Harbour Engineering》, a accurate m value can be obtained conveniently. Then based on this method and by the single factor analysis, a more systematic study was made to the related factors, and obtained the influence law of various factors to m value.

The value selection of m has a greater influence on the internal force of pile. So, how to determine the value of m is very important for the “m” method. In this paper, a geotechnical finite element software PLAXIS is used for the nonlinear finite element analysis of elastic long pile under the horizontal force action. By using the calculated maximum bending moment and the maximum displacement at the ground, and combined with the related formula for “m” method given in 《Code for Pile Foundation of Harbour Engineering》, a more accurate value of m can be obtained conveniently. Because this method is simple and practical, it can provide a useful reference for the project designer to determine a reasonable value of m.

Strength And Ductility

The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into the footing. The validation and effectiveness of PSP were verified through a series of experimental studies. The nonlinear finite element analysis was then performed to demonstrate the failure mechanism of the footing with PSPs in depth and to investigate the key parameters that affect the behavior of the footing with PSPs. Finally, the design recommendations for the footing with PSPs were suggested.

The characteristics of integral forced prformance for seel tubular high scaffold with couplers were introduced and deficiencies were pointed out in the paper. Integral forced prformance for steel tubular high scaffold with couplers was simulated by finite element software ABAQUS. Couplers joint was simulated with nolinear elastic spring element model. Eigenvalue buckling analysis was used to get the most stability capacity. The simulated result agrees well with previous experimental result.
