Best Practices of steel rebar placement

One of the most critical parts of a structure's strength and design is its steel reinforcement, which is the ideal combination of steel bars and concrete. This mixture provides stability and strength due to its tensile and compressive strength and moulding ability. Specialised designs such as cantilevered structures and thinner concrete slabs greatly benefit from steel rebar reinforcements.

Gulf Steel is a leading producer of steel rebars in the UAE.

Reinforcement bars are a mesh of steel wires that support the concrete when in tension. The exact placement of the rebar is crucial to achieving structural design performance and sustainability. To maximise the effectiveness of footing, you must consider the steel rebars' size, cover, tying and tolerance. Durability is realised when anchoring, welding, and creating bonds and hooks are done appropriately with reinforcement bars. Applying the best practices to place the steel rebars is imperative to avoid structural failures. Here are some.

Drawings

Engineers, contractors and ironworkers come together to create placing drawings for reinforcement bars. These sets of instructions must be followed diligently so that the constructed building can withstand the predicted stresses.

Concrete Cover

The concrete volume placed between the steel and the concrete member is called a concrete cover. This is what prevents corrosion of the reinforcing steel. The cover is the most crucial component to ensure that steel adheres to the concrete firmly and acquires the required strength. Verify the minimum cover needed in the Building Codes for cast-in-place concrete.

Spacing and placement

As a general rule, reinforcements should be positioned near the footing's bottom on the tension side. Check the drawing for specifics on the placement of the rebars. Before installation, you must review the structural drawings to relate them to the entire construction. The size of the reinforcement bar determines the bar support spacing, and to protect the bars from corrosion, the supports must reach the concrete at a certain depth during concrete placement. Rebar placement significantly affects the footing's ability to carry loads. Any incorrect positioning can lead to failures.

Rebar supports are available in a variety of sizes and materials. Use the right type for optimum placement.

Tying reinforcements

Rebars must be tied together to be held in place. While it does not really contribute to the strength, the process is essential to keep the rebars from shifting during installation and other construction activities. You could use an annealed or gauge wire, depending on the positioning of the rebar. Besides, not every intersection needs to be tied, and you can secure every fourth or fifth one. However, the ends of the tie wire must be away from the concrete as they could rust. Some ways of tying the rebars are:

• Snap tie – when the rebar is in a flat horizontal position
• Saddle tie – this begins at the column corner bar and stirrups to end at the beam corner bars
• Wrap and snap tie – for vertical wall reinforcement
• Figure-eight tie – used for heavy mats
