Multistory Prefabricated Columns
Concrete slabs in lift-slab buildings are cast one on top of the other, separated only by bond-breaking agents. After hardening of the top slab taken place, the slabs are lifted to their...

Floating Dry Docks for Ship Launching
Modern techniques of mechanized, prefabricated shipbuilding are compatible with a method of ship launching using a floating dry dock. This system has significant economic and operational...

Prefabricated Reducers as Entrances for Pipe Culverts
Preliminary studies indicate that flow in reducer entrance will prime naturally; resultant sub-atmospheric pressures will become effective discharge energy, sufficiently high to establish...

Tentative Recommendations for the Design and Construction of Composite Beams and Girders for Buildings
The joint committee was organized in 1956 to prepare recommendations for the design and construction of structures composed of prefabricated beams combined with cast-in-place slabs. After...
