TIMBER-ARCH FALSEWORK FOR CONCRETE ARCH BRIDGES

SIX RECENTLY BUILT 201-FT. TO 540-FT. SPAN AUSTRIAN HIGHWAY BRIDGES ARE MULTI-BOX CONCRETE ARCH STRUCTURES. THE FALSEWORK FOR ALL THESE BRIDGES CONSISTED OF PARTIALLY PREASSEMBLED TWO-TIER AND THREE-TIER TRUSSED TIMBER ARCHES. THEY WERE BUILT SUFFICIENTLY STRONG TO CARRY THE WEIGHT OF THE ARCHED BOTTOM PANEL OF THE MULTI-BOX CONCRETE ARCH. AFTER THIS CONCRETE PANEL HAD CURED, IT CARRIED THE WEIGHT OF THE WEBS AND TOP PLATE OF THE BOXED CONCRETE ARCH. WITHIN EACH TRUSSED TIMBER ARCH, NO CARPENTER JOINTS, MECHANICAL FASTENERS OR ADHESIVES WERE USED. FRICTION BETWEEN ASSEMBLIES OF 8-3/8 IN. BY 2 IN. TIMBER PLANKS RESISTED THE INTERNAL FORCES. THUS THE FALSEWORK COULD BE DISMANTLED INTACT FOR REUSE. /AUTHOR/
