Finite element model updating based on response surface methodology
This paper presents the application of central composite design based on static-load response surface method in finite element model updating for bridges.
Static load tests of bridge structures possess many special characteristics,such as little external interference,high accuracy and perfect stability,etc.
Abstract: This paper describes both the development and the mechanism of carbon fiber-reinforced polymer (CFRP), through Abaqus finite element software simulations to complete before and after joining the CFRP plate bending performance in two cases of RC beams, as well as in the loads of the load-displacement relations and stress-strain relationship, through the control of different pre-split value of working conditions, and the comparison of the data of the actual concrete beam experimental results prove that the Abaqus finite element of the feasibility and effectiveness in CFRP research, provide a reference for the actual project.

Using the static and dynamic test data simultaneously to update the finite element model can increase the available information for updating.
It can overcome the disadvantages of updating based on static or dynamic test data only.
In this paper, the response surface method is adopted to update the finite element model of the structure based on the static and dynamic test.

Using the reasonable experiment design and regression techniques, a response surface model is formulated to approximate the relationships between the parameters and response values instead of the initial finite element model for further updating. So it is very important to analyze the dynamic-static characteristic of the machine tool consider rolling guideway and to study the effect on machinery function.
