SLAB CONSTRUCTION FOR HABSYSTEM MODULES

ABSTRACT A unique precast concrete box system for buildings has been introduced in the U.S.A. Known as the HABSystem, it breaks away from the constraints of other box assemblies in that it is essentially a column and beam assembly rather than a bearing wall assembly. Production of precast slabs for the system posed a number of unusual design and construction problems. These problems were solved through a combination of approaches involving structural design, innovative forming and casting techniques, concrete mix characteristics and load tests.
