A Pre-stressing Anchorage is used as part of a structural strengthening system that aims to strengthen a building by increasing its load capacity and sturdiness. It will probably be inevitable that an old building will show signs of deterioration caused 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. Deciding on the best form of anchorage to your strengthening system will help you ensure the effectiveness of the system once installed.
The Function of Anchorages – A Post Tension Anchor is basically the introduction of high-strength cables, wires and bars to a weakened structure to be able to strengthen it. This may allow the structure, building or bridge, enabling it to transport more volumes for a longer duration of time. The reinforcements are attached to the existing structure at several anchor points which can be 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. This in turn produces a reverse loading on the structure itself.
These structure tendons bear anchors each and every end, which is made up of bearing plant that enables the structure to channel the strain from the tendons and on to the concrete. A pre-stressing anchorage are available in the ends of cables located likewise at the ends in the structure. This are is also called anchor zones. These anchors are designed to transfer the anxiety in the tendons to the new concrete jacket with the bearing, then transfer the strain from the concrete for the existing structure through sheer friction.
Installing the Pre-stressing Anchorages – Before having the ability to determine which kind of pre-stressing anchorage is to be used for the dwelling, you must conduct a structural assessment of the building to figure out its current condition. When it really has been thoroughly assessed, the outcomes will then have to be compared with the building’s current operational demands, in order to accurately define the concentration of the wedge anchor, and the amount of reinforcing needed to neutralize the damage.
In addition to that, the contractor should also be sure that the existing damage, like: corrosion, structural deterioration and erosions, have already been addressed to help make the reinforcing process effective. It must additionally be determined as to what the reinforcing system must be able to do because this will greatly determine the performance of the building once installation is done.
The pre-stressing anchorage itself needs to be designed so that you can withstand and address the bearing and bursting forces based in the anchor zones. Once the system has been installed towards the slab steel anchor, the contractor must then smtzmh the structure be able to provide a high fire rating. This might be done by encasing the cables in concrete which can emit a great deal of protection to the structure.
Refortifying a structure may be more advanced and expensive than building a new one. However, the advantages far outweighs the costs because the building can take on bigger loads and can withstand weathering damages along with other sources of deterioration a little longer. The key towards the strengthening system is based on the tendon’s capacity to take on a lot of stress. This can be made possible through the use of a top quality pre-stressing anchorage.
