A kind of force measurement mechanism which can measure the two-directional transient impact load in the same time is introduced in this paper, and the analysis research of the mechanical part are followed. First, by using the pro/E software, the 3D concrete model of the force mechanism is contributed. Then, by means of the ANSYS finite element analysis software, its stiffness and strength are analyzed, and strain and deformation figures from different directions are obtained. The static maximum deformation and strain of the force measurement mechanism and its key components, and also the whole distribution are showed in the analysis results. The weak parts of the force measurement mechanism and its key components are also showed in this paper, which can be helpful for the further improvement and following actual tests [.1]

Based on the constitutive models of steel and core concrete,the failure modes and the load-displacement curves of the solid multibarrel tube-confined concrete columns(CHS inner and SHS outer) under monotonic loading are calculated by using finite element analysis (FEA) method.The analytical results reveal the rules of stress distribution in steel and core concrete.The influences of axial compression ratio, yield strength of steel tube and concrete on the load-displacement curves are discussed.Through the results,it is deeply known the working mechanism of members(CHS inner and SHS outer) subjected to the static loads.

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.
