The prestressed circular anchor has the following advantages compared to the prestressed square anchor:

Uniform distribution of prestressed force: The prestressed circular anchorage can better achieve uniform distribution of prestressed force in design. The design of circular anchor heads and anchor rings can ensure uniform transmission of prestressing force within the concrete component, reducing the possibility of stress concentration. However, due to the stress concentration at the corners of the square anchor, it may lead to increased cracks and deformation in the concrete.

Reducing stress concentration in concrete: The shape and arrangement of circular anchors can reduce stress concentration in concrete. The circular shape of the circular anchor head and anchor ring is conducive to dispersing stress and reducing stress concentration in concrete. In contrast, the corners of square anchors are prone to stress concentration, increasing the risk of concrete cracking.

Improving anchoring effect: Due to the design of circular anchors, they can provide better anchoring effect. The contact area between the circular anchor head and the anchor ring is larger, which can better transmit the prestressing force and reduce the sliding of the prestressing steel tendon. In contrast, square anchors may require more anchoring lengths to achieve the same anchoring effect due to their smaller contact area.

Easy construction and installation: Compared to square anchors, prestressed circular anchors have a relatively simple and convenient construction and installation process. Due to its circular shape and design characteristics, installers can easily thread the prestressed steel tendon through the sleeve and fix it on the anchor head, reducing the complexity and time cost of construction.

Better adaptability: Compared to square anchors, prestressed circular anchors have better flexibility in adapting to concrete components of different shapes and sizes. Due to the fact that the design of circular anchors can better adapt to curved shapes and irregular structures, circular anchors may be more suitable for achieving prestressing effects in some special engineering projects.

Seismic performance: Due to the uniform distribution of prestressed force in prestressed circular anchors, concrete structures also have better seismic performance under external loads such as earthquakes. Circular anchors can reduce the deformation and cracking of concrete components, improve the overall stability and seismic resistance of the structure.
