For aesthetic and economic reasons, reinforced concrete tapered beams (RCTBs) are often used in reinforced concrete (RC) buildings because they offer some advantages over their prismatic elements. It is well known that as a span increase, prismatic beam would be uneconomic due to high depth. In such situation RCTB is a good …

To bear vertical and horizontal reactions from Frame by designing a tie beam we have to consider that has a general concrete beam with an axial load. This axial load works as compression or tension load so for axial compression-like axial column capacity. For required axial tension, Steel Area should also be checked properly.

Detailing is the drawing of a reinforced concrete structure, which includes showing the size, location, type, placement, splices, and termination of the reinforcement. Detailing is done in two stages. The first is the communication of the design from the licensed design professional to the reinforcement fabricator on structural drawings. The …

Precast pretensioned adjacent member bridges, consisting primarily of concrete box beams, have been in use since 1950 in the United States. Other non-box elements, including tee-beams, multi-stemmed tees, inverted tees, deck bulb-tees, solid and voided slab beams, and U-shaped beams are also used in adjacent member bridges.

Until the early 1970s, all truck scales were mechanical and installed in expensive concrete pits. Today, most scales are installed aboveground or in concrete pits with floor foundations. With the benefit of new modular construction, scales can also be installed in a shallow pit, as opposed to the deep pit required by older mechanical scales.
