Hinges#

Rotational hinges#

Rotational hinges are indicated with a circle and allow rotation between connected elements. Bending moments are not transferred while normal and shear forces are.

Rotational hinges are treated in the book Engineering Mechanics Volume 1 in chapter 4.2.1 (Hartsuijker and Welleman, 2006).

Sliding hinges#

Sliding hinges are indicated with two lines perpendicular to the elements and allow translation perpendicular to connected elements. Shear forces are not transferred while bending moments and normal forces are.

Sliding hinges are treated in the book Engineering Mechanics Volume 1 in chapter 15.4.2 with specifically figure 15.17 (Hartsuijker and Welleman, 2006).

Telescope hinges#

Telescope hinges are indicated with two lines parallel to the elements and allow translation in the direction of connected elements. Normal forces are not transferred while bending moments and shear forces are.
