expansion joints
expansion joints
(OP)
an expansion joint is introduced when the internal forces of a building due to expansion become too great. forces perpendicular to the joint are no longer possible while vertical forces and forces parallel to the joint are still possible. it is also possible to divide the two parts totally, not allowing any forces between the two parts. essentaill you have to buildings next to each other. i was just wondering if there are any preferences? if so, in which conditions and what are the advantages and disadvantages of the two possibilities?






RE: expansion joints
I would normally dowel floor joints to ensure the two sides stay in alignment and prevent a step developing.
I would probably dowel most joints by default to allow shear transfer and structural continuity; eg locate the joint at a point of contraflexure.
