Based on Static Interval Finite Element Method of Analysis of Rigid Frame Structure

Abstract:

In the framework of the actual structure of projects and inevitably there are some uncertainties. Interval finite element method can effectively function to define the scope and provide a strict mathematical sense, the results of the calculations, and finite element method for interval data can be expressed uncertainty. In this paper, the theoretical calculation of interval finite element of a layer rigid frame structure, compared the simulation results with the combination of ANSYS modeling, Numerical analysis of examples from the results of the theoretical value and the true value of the error between the results of a very small can be proved that the interval finite element theory and method for frame structures is very applicable.
