A Pre-stressing Anchorage is used as part of a structural strengthening system that is designed to strengthen a building by increasing its load capacity and sturdiness. It will be inevitable that an old building will show signs of deterioration brought on by years upon years of weathering. Because of this, there may come a time that its structure will have to be refitted and fortified in order to keep up with its operational demands. Choosing the right type of anchorage for the strengthening system will help you ensure the effectiveness of the system once installed.
The Purpose of Anchorages – A Post Tension Anchor is basically the creation of high-strength cables, wires and bars to a weakened structure to be able to strengthen it. This can permit the structure, building or bridge, enabling it to transport more volumes for an extended length of time. The reinforcements are linked to the existing structure at several anchor points that are usually located in the ends of the structure. These reinforcements strengthen the structure by generating an upward and downward force whenever there exists stress in or on the building. As a result produces a reverse loading on the structure itself.
These structure tendons bear anchors at every end, which consists of a bearing plant which allows the dwelling to channel the strain through the tendons and onto the concrete. A pre-stressing anchorage are available in the ends of cables located likewise in the ends in the structure. This are is also referred to as anchor zones. These anchors are designed to transfer the anxiety from the tendons to the new concrete jacket through the bearing, then transfer the stress from the concrete towards the existing structure through sheer friction.
Installing the Pre-stressing Anchorages – Before having the capacity to determine what sort of pre-stressing anchorage is going to be used for the structure, you have to conduct a structural assessment of the building to determine its current condition. When this has been thoroughly assessed, the outcomes will must be in comparison with the building’s current operational demands, to be able to accurately define the intensity of the dead-end anchorage, and the degree of reinforcing needed to neutralize the injury.
Aside from that, the contractor also must ensure that the current damage, like: corrosion, structural deterioration and erosions, have been addressed to create the reinforcing process effective. It must also be determined in regards to what the reinforcing system must be able to do because this will greatly determine the performance in the building once installation is finished.
The pre-stressing anchorage itself should be designed in order to withstand and address the bearing and bursting forces found in the anchor zones. Once the system has been installed to the pre-stressing anchor, the contractor must then smtzmh the structure be able to offer a high fire rating. This could be carried out by encasing the cables in concrete which could produce a considerable amount of protection for the structure.
Refortifying a structure can be more complicated and dear than building a new one. However, the benefits far outweighs the costs since the building should be able to undertake bigger loads and can withstand weathering damages along with other causes of deterioration somewhat longer. The key to the strengthening system lies in the tendon’s capacity to battle plenty of stress. This could be made possible by using an excellent pre-stressing anchorage.
