Comparisons of Experimental and Finite Element Analysis Results

Before three dimensional numerical test of four connection systems in chapter 4, the author would like to compare the experiemental test results and numerical methods. The reasons for this comparison are to check the reliability of Finite Element‘s procedures for the interaction between the node connector and beam element and to implement numerical analysis of moment-rotation behavior taking geometric and material nonlinearities more appropriate simulating method into consideration. For the implementation of the Finite Element Analysis(FEA), two node connection systems could be introduced, thanks to the data of real experiments performed by Lehmann & Keller Engineers GmbH, Germany(HEFI1) and Schlaich Bergermann und Partner Structural Consulting Engineers, Germany(SBP-3). All the procedures, which have been performed in this chapter, will be a guidline for the numerical simulation for the next chapter.
