Rib Shortening in Arches

- Rib shortening in arches refers to a phenomenon where the arch members shorten due to various reasons such as changes in temperature or lack of fit.
- This can cause stresses in the arch members and affect the overall stability of the arch structure.

Two-Hinged Arches vs. Three-Hinged Arches

- In arch structures, there are two types of arches - two-hinged arches and three-hinged arches.
- Two-hinged arches have two hinges or joints where the arch is supported, while three-hinged arches have three hinges or joints.
- The main difference between the two types of arches is that three-hinged arches can withstand greater deformations and stresses than two-hinged arches.

Association of Rib Shortening with Two-Hinged Arches

- Rib shortening in arches is primarily associated with two-hinged arches and not three-hinged arches.
- This is because two-hinged arches have only two points of support, which can cause greater stresses in the arch members due to rib shortening.
- In contrast, three-hinged arches have an additional hinge that allows the arch to deform and adjust to changes in temperature or lack of fit without causing significant stresses in the arch members.

Conclusion

- In summary, rib shortening in arches can cause significant stresses in the arch members and affect the stability of the arch structure.
- Two-hinged arches are more susceptible to rib shortening than three-hinged arches due to the difference in the number of points of support.

Stresses due to temperature and lack of fit occur only on statically indeterminate structures. Only 2 hinged arch falls into this category. 3 hinged arch is statically determinate.hope I answered the question.
