| Abstract: | There is an eccentricity when transferring the local concentrated load through one\|side fillet weld joint which connects the web and the flanges of H\|shaped steel.On the basis of test data,the validity of the FEM models are checked;the stresses in the welds and plates due to local loads are computed,and the effect of the eccentricity is quantitatively analyzed.By the results of test and computation,the simple formula for effective length of weld connecting bracket flange with column flange and the one for stress in column web are suggested.The scope of repair welding is also discussed. |
