A Pre-stressing Anchorage can be used as a part of a structural strengthening system that aims to strengthen a building by increasing its load capacity and durability. It will probably be unavoidable that an old building will show warning signs of deterioration brought on by years upon years of weathering. Due to 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 to your strengthening system will allow you to ensure the strength of the system once installed.
The Function of Anchorages – A Post Tension Anchorage is basically the introduction of high-strength cables, wires and bars to your weakened structure in order to strengthen it. This can enable the structure, building or bridge, enabling it to carry more volumes for a longer duration of time. The reinforcements are attached to the existing structure at several anchor points that are usually located at the ends of the structure. These reinforcements strengthen the dwelling by generating an upward and downward force whenever there is stress in or on the building. As a result this produces a reverse loading on the structure itself.
These structure tendons bear anchors at every end, which consists of a bearing plant that allows the dwelling to channel the stress with the tendons and onto the concrete. A pre-stressing anchorage can be found on the ends of cables located likewise on the ends in the structure. This are is also known as anchor zones. These anchors are created to transfer the stress of the tendons towards the new concrete jacket through the bearing, and after that transfer the stress from the concrete for the existing structure through sheer friction.
Installing the Pre-stressing Anchorages – Before having the capacity to determine what sort of pre-stressing anchorage is to be used for the dwelling, one must conduct a structural assessment in the building to figure out its current condition. When this has been thoroughly assessed, the results will must be in comparison with the building’s current operational demands, to be able to accurately define the concentration of the dead-end anchorage, and the amount of reinforcing needed to neutralize the damage.
In addition to that, the contractor must also be sure that the current damage, like: corrosion, structural deterioration and erosions, have been addressed to make the reinforcing process effective. It has to additionally be determined as to what the reinforcing system should be able to do since this will greatly determine the performance from the building once installation is complete.
The pre-stressing anchorage itself ought to be designed to be able to withstand and address the bearing and bursting forces found in the anchor zones. After the system has become installed towards the slab steel anchor, the contractor must then smtzmh the dwelling have the capacity to provide a high fire rating. This may be carried out by encasing the cables in concrete which may give off a considerable amount of protection towards the structure.
Refortifying a structure can be more advanced and dear than building a completely new one. However, the advantages far outweighs the expenses as the building will be able to undertake bigger loads and can withstand weathering damages along with other types of deterioration somewhat longer. The true secret to the strengthening system lies in the tendon’s capacity to take on a lot of stress. This can be made possible with the use of a quality pre-stressing anchorage.
