A Pre-stressing Anchorage is utilized as 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 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 to keep up with its operational demands. Selecting the best type of anchorage for your strengthening system can help you ensure the effectiveness of the system once installed.
The Function of Anchorages – A Post Tension Anchorage is basically the creation of high-strength cables, wires and bars to your weakened structure to be able to strengthen it. This may allow the structure, building or bridge, enabling it to carry more volumes for an extended span of time. The reinforcements are attached to the existing structure at a number of anchor points which can be usually located in the ends from the structure. These reinforcements strengthen the dwelling by generating an upward and downward force whenever there exists stress in or on the building. As a result creates a reverse loading on the structure itself.
These structure tendons bear anchors at each end, which is made up of bearing plant that allows the dwelling to channel the strain with the tendons and to the concrete. A pre-stressing anchorage can be obtained in the ends of cables located likewise on the ends of the structure. This are is also referred to as anchor zones. These anchors are designed to transfer the strain of the tendons to the new concrete jacket through the bearing, and then transfer the stress from the concrete for the existing structure through sheer friction.
Installing the Pre-stressing Anchorages – Before having the ability to determine what sort of pre-stressing anchorage is going to be used for the structure, you must conduct a structural assessment from the building to figure out its current condition. When it has been thoroughly assessed, the outcomes will then need to be in contrast to the building’s current operational demands, in order to accurately define the intensity of the anchorage grip, and the level of reinforcing necessary to neutralize the damage.
Adding to that, the contractor should also make sure that the existing damage, like: corrosion, structural deterioration and erosions, have already been addressed to help make the reinforcing process effective. It has to even be determined in regards to what the reinforcing system will be able to do since this will greatly determine the performance of the building once installation is complete.
The pre-stressing anchorage itself should be designed to be able to withstand and address the bearing and bursting forces found in the anchor zones. Once the system continues to be installed for the slab steel anchor, the contractor must then smtzmh the dwelling have the ability to offer a high fire rating. This might be carried out by encasing the cables in concrete which could produce a large amount of protection for the structure.
Refortifying a structure may be more advanced and dear than building a completely new one. However, the advantages far outweighs the costs since the building can handle bigger loads and will be able to withstand weathering damages as well as other types of deterioration a little longer. The key to the strengthening system depends on the tendon’s capacity to take on a lot of stress. This can be made possible by using an excellent pre-stressing anchorage.
