Residual Stress Effect on Link Element of Eccentrically Braced Frame


Abstract eng:
The effects of residual stress on the performance of link elements as lateral force shield, particularly for earthquake load as in the Eccentrically Braced Frame (EBF), is the main focus of this research. Experimental tests were conducted in two stages: first, the residual stress measurement of the link element with Neutron Diffraction Method methodology using the equipment of DN1-M PSTBM BATAN; second, two links were tested, a standard link that corresponds with the AISC 34110 and a modified link. Behaviours of both links were studied based on the residual stress distribution in the first stage. The magnitude of tensile stresses on and around the “k area” caused the initiation of crack on the standard link so that it decreases the performance of the link element. Modifications of the link by replacing the stiffener of vertical web with the horizontal stiffener can avoid the initiation of crack that may occur on the web plate around the “k area” so that the performance of the link elements can be improved.
