A Pre-stressing Anchorage is utilized as a part of a structural strengthening system that aims to strengthen a building by increasing its load capacity and sturdiness. It will probably be unavoidable that an old building will show signs of deterioration brought on by years upon years of weathering. Because of this, there might come a time that its structure will need to be refitted and fortified to keep up with its operational demands. Deciding on the best kind of anchorage for your strengthening system will help you ensure the effectiveness of the system once installed.
The Purpose of Anchorages – A Post Tension Anchor is basically the introduction of high-strength cables, wires and bars to a weakened structure so that you can strengthen it. This will allow the structure, building or bridge, enabling it to hold more volumes for an extended length of time. The reinforcements are attached to the existing structure at a number of anchor points which can be usually located at the ends from the structure. These reinforcements strengthen the structure by generating an upward and downward force whenever there exists stress in or on the building. This in turn results in a reverse loading on the structure itself.
These structure tendons bear anchors at each end, which is made up of bearing plant which allows the structure to channel the stress with the tendons and onto the concrete. A pre-stressing anchorage can be obtained on the ends of cables located likewise on the ends of the structure. This are is also known as anchor zones. These anchors are made to transfer the stress of the tendons for the new concrete jacket through the bearing, and after that transfer the anxiety from your concrete to 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 utilized for the structure, you must conduct a structural assessment from the building to figure out its current condition. When this has been thoroughly assessed, the results will then have to be in contrast to the building’s current operational demands, in order to accurately define the intensity of the post tension anchorage, and the level of reinforcing necessary to neutralize the damage.
Aside from that, the contractor also must make sure that the current damage, like: corrosion, structural deterioration and erosions, have already been addressed to create the reinforcing process effective. It has to also be determined about what the reinforcing system should be able to do as this will greatly determine the performance of the building once installation is complete.
The pre-stressing anchorage itself needs to be designed so that you can withstand and address the bearing and bursting forces found in the anchor zones. Once the system has been installed towards the barrel and wedge 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 could produce a great deal of protection for the structure.
Refortifying a structure may be more complex and dear than building a new one. However, the advantages far outweighs the expense because the building should be able to take on bigger loads and will be able to withstand weathering damages along with other types of deterioration a bit longer. The real key for 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.
