.... 12-31 789959 ACKNOWLEDGMENTS During the progress of this investigation, valu- able assistance was given by Messrs. E. F. Kelley and E. W. Blumenschein, engineers in the Bridge Department of the Iowa Highway Com- mission. A considerable part of the experimen- tal data were taken by Messrs. B. S. Myers and C. A. Baughman, at that time members of the instructional staff of the civil engineering de- partment, Iowa State College. LOAD CONCENTRATIONS ON STEEL FLOOR-JOISTS OF WOOD FLOOR HIGHWAY P...URPOSE The investigation was undertaken to determine the manner in which heavy wheel loads, such as those of traction engines, are distributed to the various I-beams and channels in a highway bridge floor system con- sisting of I-beam and channel joists and wood planking. While this is a type of bridge floor that is no longer employed for main highways if its use can be avoided, it is still employed to some ex- tent on secondary roads. A large number of such bridges now in ser- vice are of such design that the trusses will not carry the additional dead load resulting from the addition of a concrete floor, and the wood floor must be maintained or the bridge replaced.
