Behavior of reinforced concrete tapered beams

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 …

Truck Scale Foundations

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.
