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 durability. It will be inevitable that an old building will show warning signs of deterioration caused by years upon years of weathering. For this reason, 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 type of anchorage to your strengthening system will help you ensure the strength of the system once installed.
The Purpose of Anchorages – A Barrel And Wedges is essentially the development of high-strength cables, wires and bars to some weakened structure to be able to strengthen it. This can allow the structure, building or bridge, enabling it to transport more volumes for an extended length 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 structure 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 each end, which consists of a bearing plant which allows the dwelling to channel the stress through the tendons and on to the concrete. A pre-stressing anchorage can be found at the ends of cables located likewise on the ends from the structure. This are is also called anchor zones. These anchors are made to transfer the stress from the tendons for the new concrete jacket from the bearing, then transfer the stress from your concrete for the existing structure through sheer friction.
Installing the Pre-stressing Anchorages – Before having the ability to determine what type of pre-stressing anchorage is going to be used for the structure, one must conduct a structural assessment from the building to determine its current condition. When it really has been thoroughly assessed, the results will likely then need to be compared with the building’s current operational demands, to be able to accurately define the power of the dead-end anchorage, and the level of reinforcing needed to neutralize the injury.
In addition to that, the contractor must also make sure that the current damage, like: corrosion, structural deterioration and erosions, have already been addressed to create the reinforcing process effective. It should even be determined as to what the reinforcing system must be able to do since this will greatly determine the performance from the building once installation is finished.
The pre-stressing anchorage itself ought to be designed in order to withstand and address the bearing and bursting forces located in the anchor zones. When the system continues to be installed towards the slab steel anchor, the contractor must then smtzmh the structure have the capacity to provide a high fire rating. This might be done by encasing the cables in concrete which could produce a great deal of protection to the structure.
Refortifying a structure may be more complex and dear than building a completely new one. However, the benefits far outweighs the expense since the building can take on bigger loads and should be able to withstand weathering damages as well as other causes of deterioration a bit longer. The true secret for the strengthening system depends on the tendon’s capacity to consider lots of stress. This could be made possible by using a quality pre-stressing anchorage.
