ABSTRACT:
A method of producing a cambered composite joist and concrete panel assembly, and the assembly so produced, comprising the steps of providing a negatively cambered casting mold, positioning at least one negatively cambered composite joist with a bottom chord joined to a web member having non-attached top apices into the mold such that the top apices rest within the mold, pouring concrete into the mold and allowing it to harden to form a cambered concrete panel with the joists extending from the panel, removing the assembly from the mold and inverting it such that the precast camber in the panel flattens out from the effects of the weight of the panel and creep during final curing.
