rebar construction
Honeycomb Beams
Honeycomb beams are beams manufactured by sliding two parts obtained by cutting hot rolled H and I type profiles zig-zagged along their bodies and reassembling them with welds. It is also possible to weld square or rectangular plates between the cut halves, giving a deeper crenellated beam that results in octagonal openings in its body.
Advantages
- They increase the vertical bending rigidity.
- Although they have the same weight compared to normal section beams, their section inertia is greater.
- There are many areas of use from short spans to long spans.
- In multi-storey buildings beam bodies installation works are facilitated as the gaps allow pipe passage.
- Concrete deck the total laying depth is reduced.
- Thanks to their elegant appearance, they can be preferred in cases where the appearance of the beams is inevitable.
- Due to the large cavities in the casing, they have different structural behaviour compared to beams with solid casing.
- Caution should be exercised in conditions where point loads are evident.
- It is necessary to pay attention to the use in places where stress accumulations at the corners of the voids are subjected to dynamic loads. In this case, the use of honeycomb beams with circular eyes can be considered
