PREDICTION OF THE PERFORMANCE OF SHEATHED SHEAR ELEMENTS REINFORCED WITH SHEAR KEYS ALONG PANEL JOINTS AND IT'S VERIFICATION WITH NUMERICAL ANALYSES

Simplified formula to predict the performance of sheathed shear elements reinforced with shear keys along panel joints is derived in this paper. The formula is verified by numerical static elasto-plastic analyses for various values of the ratio C of the stiffness of nails to that of shear keys. Results predicted by the formula that consider the behavior of all panels well agree with those by numerical analyses. The formula becomes complicated as the number of panels increases. When the formula is simplified, the validity of the formula depends on the number of panels and the value of C.
