Review Guidelines for Design of Joints
- How is the total movement need calculated? (Temp, shrinkage, other)
- How is the temperature range determined?
- How is skew dealt with?
- What types of joints are specified by designers?
- Small movements (< 2")
- Moderate movements (2" to 4")
- Large movements (> 4")
- Is a Qualified Products List used to prequalify acceptable joints?
- What considerations are made to make the joints watertight, or handle the water?
- What considerations are made for construction tolerances of the joints?
- Does the type of bearings used and direction of permitted movement taken into account?
- Are manufacturers of modular or steel finger joints required to be certified under AISC Quality Certification Program, Category 3, Major Steel Bridges?
- How are maintenance and replacement of joint parts accounted for in design and selection of joints?
- Is fatigue of large joints considered? If so, how?
- How has the State's experience with the performance of joints affected their current design procedures?
- What does the State see is the greatest deficiency in the design of joints? How can that be improved?
- Does the State use warranties in specifying joints? If so, what is their experience to date?
