MOMENTS, SHEARS AND REACTIONS FOR CONTINUOUS HIGHWAY BRIDGES

ENGINEERING CONSIDERATIONS FREQUENTLY LEAD TO THE ADOPTION OF CONTINUOUS STRUCTURES AS THE MOST EFFICIENT SOLUTION OF A DESIGN PROBLEM, BUT ANALYSIS OF SUCH STRUCTURES OFTEN BECOMES MORE TIME-CONSUMING THAN THAT OF SIMPLE STRUCTURES. THIS IS PARTICULARLY TRUE IN THE CASE OF HIGHWAY BRIDGE SPANS OF LENGTHS SUCH THAT TRUCK RATHER THAN LANE LIVE LOADING GOVERNS THE DESIGN. THE TABLES CONTAINED HEREIN WERE PREPARED TO ASSIST THE DESIGNER OF CONTINUOUS BEAMS AND GIRDERS IN GENERAL, AND CONTINUOUS HIGHWAY BEAM BRIDGES IN PARTICULAR, BY REDUCING THE TIME REQUIRED FOR ANALYSIS. EXPERIENCE GAINED THROUGH CONSTRUCTION OF A LARGE NUMBER OF GRADE SEPARATIONS IN THE INTERSTATE HIGHWAY SYSTEM HAS INDICATED THAT APPRECIABLE ADVANTAGES RESULT FROM THE USE OF TWO-SPAN RATHER THAN FOUR-SPAN STRUCTURES. /AUTHOR/
