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.

4 finite element models of ANSYS were constructed according to the masonry wall specimens of the experimental study. A material nonlinear finite element analysis by the finite element calculation software ANSYS on masonry walls strengthened by SGFRP under the horizontal cyclic loads combined with constant gravity loads was performed. The load-displacement curves of the models obtained from ANSYS simulation were described. The ultimate loads of the 3 models strengthened by SGFRP increased significantly, and the fiber length affect the bearing capacity and the deformation capacity of the wall. The results of the nonlinear finite element analysis of the models agree well to the experimental results. Some effective and reasonable reinforcement suggestions are proposed.

Rigid Joints

In conventional analysis and design, the beam-column connections are divided into two categories: fully rigid joints and perfectly pinned joints. Actually, most beam-column connections exhibit flexibility. Idealized connections may diverge from the real reaction of structures. This article presents a hybrid finite-element model that consists of a beam element with two semi-rigid connections at the ends for studying the effect of the flexibility on the structures. Based on the theory of finite deformation, the first-order and the second-order stiffness matrix and the equilibrium equation of hybrid beam element were got. A nonlinear finite element analysis program was developed to analysis the steel frames with semi-rigid connections. At last, one-bay, two-story semi-rigid planar steel frame was analyzed using the program, and some conclusions about the effect of semi-rigid connections flexibility were obtained.
