Exposed Column-Base Plate Connections Bending About Weak: II. Experimental Study
Dae-Yong Lee,Subhash C. Goel,Bozidar Stojadinovic 한국강구조학회 2008 International Journal of Steel Structures Vol.8 No.1
Four exposed-type column-base plate conection sub-asemblages (two for 6-bolt connection and two for 4-bolt conection)were tested under the SAC Phase II loading history in the direction of column weak axis. Mainly investigated in thisexperimental study were global cyclic performance of each test specimen and behavior of major conection elements underlarge column lateral displacements. Also examined were effects of diferent number of anchor bolt, diferent relative strengthone of the four specimens completed the applied entire loading history without significant strength degradation and formed aplastic hinge at the bottom of the column. The other thre specimens showed a limited ductility in the connection. Throughthe experimental study, the Drake and Elkin’s design method that was used for design of the test specimens was evaluated andseveral major findings from the numerical parametric study presented in the companion paper, which is published together,were verified.
