Study on the Determination Method and Influence Factors of m Value Based on Nonlinear Finite Element Analysis

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.

In this paper, nonlinear finite element analysis on the steel frame with top-seat angle and double web-angles semi-rigid connection were carried out with ANSYS finite element software. In the analysis, connective, geometrical and material nonlinear were considered. Compare analysis results with experimental results, the influence of semi-rigid connection’s flexibility on steel frame was studied and some references to the design of steel frame with semi-rigid connection were supplied.

Selection Of

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.
