Tins is then known as the T-beam type of construction, fromits resemblance in form to the capital letter T. The tops of the let-ters are built adjacent to each other or in one continuous slab in sucha way as to form the floor for the structure. These types of concrete construction may be strengthened furtherby placing steel rods, expanded metal, or woven-wire cloth near thebottom of the slab, and steel rods near the bottoms of the advantages of using the steel reinforcement are that it has agreater tensile strength than concrete and that its location in thelower part of the concrete slab or beam brings it into tension when the Bui. 43, Office of Public Roads, U.
