What type of joint is characterized by interlocking fingers within steel plates?

The correct answer is characterized by its design, which involves the interlocking of fingers within steel plates, providing a specific type of mechanical connection. This type of joint is typically used to transmit loads effectively while still allowing for some relative movement or adjustment in the structural system.

In assembly joints without a seal, the interlocking fingers allow components to come together firmly but without the additional features that would seal them from environmental factors, such as water or debris. This is significant in the context of bridge inspections because these joints must be regularly assessed for wear, load transfer capabilities, and potential corrosion issues that could affect their integrity over time.

Understanding the design and function of assembly joints without a seal highlights their importance in maintaining the overall performance of a structure without compromising the ability to manage movement due to thermal expansion or other factors.
