ABSTRACT:
A composite girder is described which has a steel Wide Flange beam with the top flange of the Wide Flange beam being embedded in a reinforced concrete compression member that completely encases the top flange of the Wide Flange beam and also encases a portion of the web of the Wide Flange beam adjacent the top flange. The composite girder is intended for use in constructing parking garages and has a unique slope of the upper surface on the concrete compression member to permit drainage of floors constructed when pre-stressed, precast concrete double tees are utilized to span the distance between adjacent composite girders. Apparatus and a method for forming the composite girder in the field have been devised which include the erection of a temporary concrete form support above the steel Wide Flange beam and the pouring of the concrete to form the concrete compression member while the temporary form is in place. The elements of the temporary form and its support may be readily transported by truck before assembly and erection.
