Abstract

Structural joints provide connection between structural element (beam, plate etc.) in order to construct a whole assembled structure. There are many types of structural joints such as bolted joint, riveted joints and weld joints. The joints structure significantly contribute to structural stiffness and dynamic behavior of structure hence the main objectives of this paper to review on method of model updating on joints structure and discussed the guidelines to perform model updating for dynamic analysis purpose. This review paper firstly will outline on some of existing finite element modelling works of joints structure. Experimental modal analysis is a next step to obtain modal parameters (natural frequency & mode shape) to validate and improving the discrepancy between results obtained from experimental and the simulation counterparts. Hence model updating will be carried out to minimize the difference between the two results. There are two method of model updating; direct method and iterative method. Sensitivity analysis employed using SOL200 in NASTRAN by selecting the suitable the updating parameters to avoid ill-conditioning problem. It is best to consider both geometrical and material properties in the updating procedure rather than choose only a number of geometrical properties alone.
