Partially encased composite steel I-girder with steel bars welded to the flanges has been proposed and studied by experiments and analyses. The partially encased girder had 2.08 times higher' bending strength and 2.98 times higher shear strength than the conventional steel I-girder. When the steel bars were not welded to the flanges, the bending strength was less than the encased girder with welded steel bars but still 1.75 times higher than the steel I-girder. When the deformed I-girder was filled with concrete, the bending strength was improved with I.89 times of the steel I-girder. The analytical methods have been proposed to assess the bending and shear strength and the calculations agreed well with the experimental results..
