About Steel Structure Technology
About Steel Structure Technology-- Footing anchors for building foundations, how to avoid being pulled out.
Steel Structure building Anchor bolt damage form: What are the forms of damage that may occur to footing anchors pre-buried in concrete foundations of Steel Structure Shed that are subjected to tensile forces?
Structural steel anchor bolts are pulled bad anchor bolt itself will break or produce obvious plastic deformation. This situation may be the steel structure shed load and anchor bolt with small, or steel quality problems.
Steel Structure building Anchor Bolt Pulled Anchor bolts are pulled right out of the concrete. Steel structure anchor bolts are large enough that transmitting the tensile force depends on the bond with the concrete. When this bond is insufficient (e.g. low concrete strength), the steel structure shed anchor bolt cannot be firmly anchored in the concrete.
Steel Structural building concrete ruptures around the anchor bolt, and the concrete peels off as a whole or crumbles in large pieces. Steel Structure shed anchor bolts are large enough and have a strong enough bond, When the anchor bolt is under tension, this force is transferred to the surrounding concrete. If the concrete is not strong enough or does not have enough reinforcement, the concrete around the steel Structure anchor bolt will crack and fall off in one piece.
Steel Structure shed concrete splitting concrete can develop linear cracks along the perimeter of the anchor bolts. This is usually due to improper positioning of the steel Structure building anchor bolts (e.g., too close to the edge of the concrete) or pre-existing cracks in the concrete, resulting in localised concentrations of stress.
Steel Structure building Concrete Side Spalling When anchor bolts are installed close to the edge of the concrete, the circular pattern of rupture of the concrete cannot be fully formed when the anchor bolt with the nut at the bottom is subjected to tensile force, and this results in the concrete spalling or bursting sideways first. So make sure there is enough reinforcement around the edge to prevent side bursting, especially if the anchor bolt is a short distance from the edge.
Bond Damage When the bond interface between the steel strcuture shed anchor bolt and the concrete fails, the reinforcing two-dog anchor bolt is unable to effectively transmit tension to the concrete. This bond failure is usually caused by improper construction, such as failure to clean the surface of the steel structure anchor bolt.
Proper steel structure design can achieve overall co-ordination of redundancy and economy in all aspects, and it is easy to overlook other possible areas of weakness if one aspect is overly strengthened.
