THE CASE FOR THE SEMI-BOX GIRDER
THE SEMI-BOX GIRDER IS THAT BREED HAVING A PARTLY OPEN AND A PARTLY CLOSED CROSS SECTION. AS SUCH, IT IS NOT AS TORSIONALLY STIFF AS A RECTRANGULAR BOX GIRDER,BUT SUBSTANTIALLY STIFFER IN THIS REGARD THAN AN OPEN SECTION. ITS MAIN ATTRIBUTE IS ITS ABILITY TO RESIST FAILURE BY LATERAL TORSIONAL BUCKLING AND, AS SUCH, IS USEFUL IN BRIDGE WORK TO FACILITATE ERECTION, OR IN OTHER INSTANCES WHEN THE GIRDER IS USED IN AN ISOLATED CONDITIONS, SUCH AS IN A MONRORAIL OR CRANE GIRDER. THE PURPOSE OF THE PRESENT ARTICLE IS, FIRST, TO DESCRIBE AN APPLICATION INVOLVING A CRANE RUNWAY; SECOND (AND MOST IMPORTANT), TO ILLUSTRATE THE EASE OF HANDLING THE DESIGN OF THIS TYPE OF CONSTRUCTION AND THUS ENCOURAGE ITS USE; AND LAST, TO SUGGEST CODIFICATION RULES. /AUTHOR/
