Oregon Bridge Features Innovative Bell Piers, Floating Falsework
The I-205 bridge, scheduled for completion in 1983, will be a final link in a 40-mile highway east of Portland, Oregon. the substructure and superstructure design featured unusual technology....

Design and Selection Considerations for Concrete Falsework
Modern cast-in-place concrete construction often requires the use of sophisticated falsework systems which carry significant and complex loadings. Since these falsework systems must satisfy...

Proof-Loading of Scaffolding
When a scaffold system that is free to sway is tested to demonstrate its strength and stiffness, serious errors can occur if the load is applied by jacks with tiebars or cables. Experiments...

Bridge Erection by Launching is Fast, Safe, and Efficient
The construction of long prestressed concrete bridges without using formal falsework or self-supporting launching falsework is described. Using the so-called incremental launching method...

Falsework Eliminated in Bridge Erection
The U.S. Highway 50 bridge just east of North Vernon, Ind., is one of the first applications in this country of the precast, prestressed concrete box girder design erected without falsework....
